.
- Ruth is impressed with me.
She offered me the council seat.
- Why would she do that?
- Why can't you just be happy for me?
- Maybe whoever sent that message was never
trying to help us find Eve.
Could be they only want the information
inside your head.
- Microchip, and I--
I think I was stealing it.
- The government was conducting
time travel experiments.
You and a handful of pilots were at the center
of testing that technology.
- I just time traveled to 2021 from the Ice Age.
And you worked on a classified project
at Ladera airbase.
There's a connection there.
- Maybe Ladera has the answers we're looking for.
- The three of us can help to bring everyone home.
The lives of the people you love depend on this.
- If there's a way to get us onto the base,
I'm gonna find it.
[dramatic music]
* *
[horn honks]
* *
- I don't like this.
Gavin's contact should be here.
- Maybe he got cold feet.
We are asking him to break us into an Air Force facility,
give us access to a classified project.
- Something doesn't feel right.
I'm giving it five more minutes,
then we pull the plug.
- Yeah.
[indistinct chatter]
- Oh, my God.
Gavin Harris?
- Sorry, do I know you? - Come on, man.
I used to drink you under the table at the Black Boar.
- There.
- Who's this?
- [laughs] How the hell are you?
- Hey, I'm sorry, I'm actually meeting someone.
- Totally understand.
I'll just keep their seat warm till they get here.
Don't worry about your meeting.
He won't be coming.
* *
- OK, what exactly is this, huh?
Who are you?
- I'm the woman you're going to follow out the back door.
Move. Now.
- Right.
And if I say no?
[pistol cocks]
- I don't think you will.
* *
- Why are they leaving? - Let's go.
* *
- Excuse me.
[tires screeching]
- Watch out!
[tires screeching]
* *
- Sam, is all this lab rat stuff really necessary?
- Your pulse is still high.
Your breathing's shallow and your skin's clammy.
So yeah, it is. Let me see your eyes.
[laptop chimes]
[tense music]
* *
- "Did you find Sierra?"
- Find out who the hell they are.
- "I know Sierra is Maya Schmidt.
Who are you?"
- "The person that has your wife."
- Son of a bitch.
"What do you want?"
* *
"She did."
"Find the microchip."
* *
- Gavin.
- That microchip I remembered,
what is it?
- I told you yesterday how the military
was weaponizing time travel.
That microchip is the key to all of it.
- What do you mean?
- They recruited pilots like Gavin
because they wanted to put that tech into planes,
make an entire fleet of time machines.
That microchip contains all the code to make it possible,
at least that was the hope, until it went missing.
- So you're saying the chip I stole was the prototype?
- Yes.
Gavin, do you have any idea where you put the chip?
- No. No, I don't remember.
- You sure?
- All I know is, it's not here.
And if I stole it from back home,
then that's where it is, which means
I have no way of finding it.
- Wait, wait, wait.
I wouldn't rule it out completely.
There could be a way to get a message to you there.
- How?
- The Tar Pits.
Listen, they're constantly being excavated.
We put a message in there, it could get to you.
- Sam, that's insane.
- It worked once before, didn't it?
Besides, what do you have to lose?
- Dad. Dad.
- Iz, what's going on?
- Dad, look. Come on, you need to see this.
Leyla and I were out hiking and saw a big fire.
It's just over those mountains.
[suspenseful music]
- That's only a few miles from the fort.
- It's coming this way.
* *
[dramatic music]
* *
.
[tense music]
* *
- We don't have another choice.
Everyone has to evacuate.
Go with this group. We'll be right behind you.
- Sam, Gavin took Izzy, Maya, and Scott to the Tar Pits
and they're gonna meet us at Bald Ridge,
the highest peak in the area.
- That's good. That's where everyone's headed.
You two are with me. Grab Veronica.
We move out in five. - Got it.
[indistinct chatter]
- OK, all of these.
- You're sure you can handle this?
- Absolutely.
- Veronica. Hey.
Listen, I came to apologize.
I didn't think before I spoke.
You deserve to be on the council.
It's good for you. It's good for the family.
- That means a lot.
[birds squawking]
- It looks like the animals are fleeing the fire.
Hey, Sam wants us to be ready to leave in five.
- Can I have ten?
The council needs to do one last sweep before we leave.
I feel like I'm in this trial phase with Ruth.
I want to do this right.
For the first time down here, I feel like
I have some kind of purpose.
I don't want to blow it.
- Hey, you're not gonna blow it.
You're great.
I'll meet you by the gate? - Yeah.
- OK.
[indistinct chatter]
- Once we get this message into the Tar Pits,
we head to Bald Ridge, meet up with everyone else.
- Aye.
- Are you worried it won't work?
- I'm more concerned that the message is addressed to me.
- Believe me, I know this sounds
like a crazy plan, but you said
you've got friends who work at the Tar Pits
and they can get the message to you, right?
- Yes to all of that.
It's more the me that I'm worried about.
That period of my life wasn't exactly one I'm proud of.
I'll spare you the gory details,
but let's just say that I was consumed
by a darkness that made me a much different man
than you see today.
I just don't know if that version of me
will come through for you.
- Have a little faith, Scott.
[soft music]
* *
- Hey, listen.
Petra, she's a really great kid--
smart, kind,
and all she wanted was to find you.
I swore I'd help her, but now she's gone.
- Which is not your fault.
Hey, I am going to get my daughter back.
- And I'll help however I can.
- That's very kind of you.
- There is something else I've been wanting to ask.
- About the meeting we were supposed to have.
You want to know why I reached out to you.
- Yes. I want to know.
What's my place in all of this?
- The truth is, I was told to recruit you to the program.
- But what would a time travel project want
with an anthropologist?
I mean, not exactly my skill set.
- I don't know specifically.
But those decisions were made above my pay grade.
I'm sorry.
I wish I knew more.
- The tar pit's up here!
- Come on.
[tense music]
* *
[tar pit burbling]
- Well, ladies and gentlemen, in several thousand years,
this will become Tar Pit 9,
the most heavily excavated site at the museum.
- OK.
Now what?
- Now we pray to whatever gods we hold dear
and send this message on a little trip through time.
* *
- OK.
We better move.
* *
- Pick up the pace.
[animal whining]
- Hey, Sam. Sam.
Check it out.
[soft music]
It's a puppy.
Hey, buddy.
- That's a wolf.
- Yeah, a wolf puppy.
Look, he's friendly.
[wolf whining]
- The answer is no, we're not bringing it with us.
- Sam, he's not gonna survive out here on his own.
- Last thing we need is an animal to drag us down.
We keep moving. Dog stays here.
Let's go!
[tense music]
* *
- It's OK. Hey, I got you.
It's OK, buddy.
[wolf whines]
You're safe now, huh?
- Yeah. OK, great.
Keep me posted. Thanks.
- I checked the parking lot for any clues
who might have taken Gavin.
I found his phone.
But I can't open it.
- I just talked to a buddy at LAPD.
He's putting out a BOLO on that woman's car.
- So a wing and a prayer.
Gavin was our one way onto that base.
- Hey, I know how hard it is
having your friends' lives in your hands.
Believe me, I've been there.
- It's not just my friends I'm failing.
I met someone. An amazing woman, Paara.
We were married, and now I'm terrified
I'm not gonna find my way back to her.
[somber music]
- Gotta be rough,
not knowing what the future holds.
* *
Can I ask you something about my future?
- Yeah.
- Here, I feel like I'm failing Riley as a dad.
I just want to know if I find a way to be a better one.
- You two have come a long way.
- So she's OK.
She's safe.
- Sam, I believe if we're successful,
we're going to save all the people we love.
[phone ringing, vibrating]
- Hey, is that Gavin's Air Force contact?
- No, it's our friend.
Another person who fell in the sinkhole.
- Well, that can't be a coincidence.
- I don't believe it is.
- Hello?
- Gavin, you don't know me,
but I have an amazing story to tell you.
.
- So you're saying Gavin was kidnapped?
- Yes, but we're trying to get him back.
He's our friend.
- From 10,000 B.C., where we all met.
- I get it.
I had the same reaction when he told me,
but it's true.
- Mm-hmm.
This time travel thing,
"Terminator" or "Back to the Future" rules?
[quirky music]
- I'm not sure what that means.
- Is it string theory, single timeline, multiverse?
- Listen, you said you got a message through the Tar Pits
for Gavin, right?
We need to know what it says.
- We're trying to find a way to get our friends home.
That message might help us.
- That message told me to find Gavin Harris, not you two.
I have no idea who the hell you are.
This is way too important to let it slip
into the wrong hands.
- I told you.
We're his friends.
- I have seen every time travel movie there is to see,
and that is exactly something a villain would say.
- We are not villains.
- Well, you've got the British accent.
- Scott. - And you can't tell me
where Gavin is.
And you've got this crazy freaking story
that no one in their right mind should believe.
That message was given to me for a reason,
and I'm not gonna risk handing it over to two randos
that I've never seen before in my life.
[phone vibrating]
Finally.
Excuse me.
* *
My lunch is here.
It's time for you to go.
- I understand your hesitation,
but I'm gonna earn your trust.
- By stealing my pizza?
- No, by making you a proper lunch.
* *
- [coughing]
[wolf whining]
[soft dramatic music]
* *
- Sam.
Hey, you cool?
- I'm fine.
Let's get going.
- Not until I know you're gonna be OK.
- Well, I can't promise anyone's gonna be OK.
You know, you should lead them, Lucas.
You're the one they trust.
- Dude, I don't know anything about fire.
- None of us do.
It's completely unpredictable.
I mean, it takes whatever or whoever it wants.
- Took something from you.
- Riley was only ten years old.
The blaze took out the cell towers
before the emergency alert went out,
so the first I knew about the fire
was when I saw it cresting the hill
on the top of my street.
In barely a minute, it was at my door.
All I could do was throw my wife and kids in a car
and drive.
But the smoke...
it was so thick.
I was blind.
I had no idea where I was or if we'd even get out.
- You did get out.
Is something else going on, Sam?
- Let's go.
* *
- So we have a choice.
[indistinct chatter]
- Hey, what's going on?
- We thought there was a chance
the fort would be spared, but no longer.
My scouts say the winds have shifted in the lower valleys.
The fire is coming.
- What are you gonna do now?
- There's a river near the fort where we draw water.
We've made a dam there, but if we break it free--
- You'll flood the woods near the fort, maybe stop the fire.
- It's our only hope now.
- You go back to that river,
you're heading right into the flames.
- That's why only a small group from the council volunteered.
- You can count me in.
- Hey, we need to keep you and the baby safe.
- This is our home. We have to protect it.
- OK, well, I'm coming with you then.
- Hey, it's only a few more miles to Bald Ridge.
You get the group there. I'm going with them.
[intense music]
[wolf barking]
* *
[triceratops grunting]
- Just about everything in 10,000 B.C.'s
fleeing that fire.
[triceratops roaring]
[coughing]
- Hold up, you guys.
- [coughing]
- Hey, hey, you all right, bud?
- [coughs] I'll be fine.
- This smoky air is not helping.
- There's a river down there.
I've got shirts in my backpack that we can strip and soak
to work like air filters.
- Good thinking.
Let's go. Give you time to rest.
- [coughs]
- All right, let's sit down.
- [breathing heavily]
- Still feeling off from yesterday?
- Yeah.
[coughs]
- All right, just relax.
Slow your breath down.
- [breathing deeply]
- In and out.
- [grunting]
- [echoing] Dad?
Dad, are you OK?
- [groans]
[mysterious music]
* *
[grunts]
- Dad?
What happened?
[tense music]
* *
- [breathing heavily]
Who the hell are you?
- My name is Helena.
- I didn't ask what your name was.
I asked who you are.
- That you wouldn't believe--
not yet, at least.
But I can tell you something about yourself.
You willingly signed up to do horrible things.
- No, no, I'm not that type of person.
- You are,
when it's the only way to stop something worse
from happening.
- Like what?
- A military funded a program
to turn fighter jets into time machines.
Think how dangerous that could be.
As their lead civilian consultant,
I made certain you were shortlisted
to be a test pilot.
- What expertise could you possibly have in time travel?
- We'll get to that.
Once we were on board, we came up with a plan
to dismantle the project from the inside.
We did this together, just you and me.
We were going to help the world,
or at least make sure these people didn't destroy it.
We're the good guys, Gavin.
[soft dramatic music]
- I don't believe you.
* *
- For now.
But I'm about to show you proof you won't be able to deny.
* *
.
- [coughing]
- Whoa, whoa, why aren't you resting?
- Scott, did you write a paper called "Universal Flora"?
- What? How do you know that?
- I'm remembering more about the program.
They have a copy of your paper.
- Well, I don't know how. I--I never published it.
- What was it about?
- Just boring ethnobotany stuff--
extinct plants and their regenerative properties,
but nothing to do with sinkholes, auroras,
or time travel.
- No, this doesn't make any sense.
There must be more to it.
- Do you remember who told you about it?
[mysterious music]
* *
- I don't know who it was.
Somebody just showed it to me.
They had some scars on their arm,
three of them, right there.
Does that mean anything?
[fire whooshes]
- Oh, my God.
- We have to get to Bald Ridge, where it's safe.
- Maya's still by the river.
- Well, let's go get her.
[coughing]
- No, you guys go ahead.
I'll get her and we'll catch up with you.
- Are you sure? - Don't worry. I got this.
[keypad beeping]
- The account number you provided
gives access to this safety deposit box here,
number 352.
[tense music]
* *
Your thumbprint authentication opens the final security lock.
I'll give you both some privacy.
- What are we doing here?
Why does this feel like some kind of trick?
- It's not, Gavin.
I just need your thumbprint.
- My thumbprint.
I thought you were gonna show me some proof.
- That's exactly what this is.
I told you we did this together.
I was telling you the truth.
Your turn.
* *
[lock clicks]
Want to do the honors?
* *
Now do you believe me?
* *
- The dam's just up here.
[wolf barks]
This pulley system is how we release the water.
- You've got a big problem here.
The pulley system is damaged.
There's no way to yank up the gate
and no way to release any of that water.
- I mean, we've got to do something, man,
because that fire's gotta be closing in on the fort by now.
* *
- We don't need to fix it. We need to damage it.
Sam, you still have that gun? - Yeah.
- You think there's enough gunpowder in those bullets
to make an explosive, loosen one of those support beams?
* *
- That's not a bad idea.
Pack the powder into the bottle, shoot it,
could cause some damage.
[booming]
[wolf whining]
- He's heading toward the fire.
- Damn it.
- Sam. Sam!
- What do we do?
- You help Ruth.
I'll be back as soon as I can.
* *
.
- Try it.
- I really don't need you to make me lunch.
- You don't need lunch, but you do need comfort.
That's what this is.
You told me your mum made this for you
when you'd have a bad day at school--
cheddar, brie, a sprinkling of chaat masala.
[somber music]
- Why do you think I need comforting?
- Something's weighing on you.
Your apartment's a mess.
The video games, the comic books--
you told me they became a crutch
after your older brother passed away,
how you'd use them to escape
whenever a problem would come up
instead of facing it head-on.
And these, brittlebush flowers--
fresh flowers amongst all of this.
Scott, why do you have them?
- OK, I think you need to leave.
- Back in 10,000 B.C., we passed through a field
of these same flowers.
Your mood suddenly changed,
and I saw you pull something out of your wallet
and stare at it.
Scott,
I know this is about a girl.
* *
- Yeah, you got me, Sherlock.
* *
- She broke your heart.
- It's a little more complicated than that,
but I lost the best thing in my life.
Since then, I guess I've just given up on everyone.
- It sounds to me more like you've given up on yourself.
- Scott, clearly people haven't given up on you.
They sent you that message from 10,000 B.C.
because they believe in you, because they're your friends.
- I know it's hard to see right now,
but we are your friends.
You can trust us.
Please.
Let us see the message.
- "To Scott Israni,
"call an Air Force pilot named Gavin Harris.
"His phone number is 951-555-0196.
"Tell him he hid an important microchip
"and that finding it is the only way to save his wife.
"At all costs, he must find a way
"to get that chip to 10,000 B.C.
"Good luck, Scott, and thank you.
Gavin Harris."
Freaking weird, right?
I mean, what's the deal with this microchip?
And why does it have to get to 10,000 B.C.?
- I don't know, but it sounds like Gavin does.
- Maybe that's why this woman took him.
Sounds pretty damn important.
[phone ringing]
It's my buddy over at LAPD.
Let's see if he found that car.
- You asked me who I was earlier.
I think you're ready to hear what you knew
before your memory was wiped.
All of this is linked to our family's legacy.
- What do you mean, "our family"?
- Gavin...
I'm your sister.
[soft dramatic music]
- You're kidding me.
- Half-sister, technically.
You're the only family I have in this world.
Our father, he wasn't a parent to either of us.
What he really cared about was his work.
- What work was that?
- Time travel.
He didn't care about the damage it caused,
but you and I still felt
the responsibility of his choices.
He built his empire off the bones of this project.
Their science inspired him to build
his own version of time travel,
which had terrible ramifications.
That's why we wanted to stop all of this.
And we still can.
I still have access to the program's network.
What are you thinking now?
* *
- That's a lot.
But I'm glad I know the truth.
- Come on.
There's one more thing I need you to see.
- Here, boy!
Hey!
Come here, boy!
Come on!
Here, boy.
[tense music]
[fire whooshing]
Where are you?
Here, boy!
[barking]
There you are.
Good boy.
- [coughs]
Sam! Sam!
- Over here.
It's OK.
- Dude, what are you doing?
- I can't lose anyone else.
- What are you talking about?
- I didn't get everyone out that day.
Once we cleared the flames,
that's when Riley asked about our dog,
and I realized I forgot him.
She begged me to go back, even reminding me
SEALs never leave a man behind, but I did.
I failed her, just like I'm failing her now.
- Sam, the only way you're failing her
is if you don't get out of here alive.
[trees cracking]
* *
Sam. Sam, we gotta go, now.
- No, no, no, we can't.
* *
- [exhales deeply]
- Are you sure this will work?
- We're about to find out.
* *
[gunshot]
[exhales deeply]
[gunshot]
[dramatic music]
* *
[gunshot]
Come on!
[wood cracking]
Come on!
[wood cracking]
[laughs] Yes!
[hopeful music]
* *
- Good work, Veronica.
* *
[energy crackling]
- Impressive, isn't it?
- What is it?
- It's the doorway to another time.
Two times, specifically.
Go through the blue, you're in 10,000 B.C.
Go through the red, you're in 1965.
[mysterious music]
That's where we're headed.
- '65?
Why?
- Because that's where the program originated.
To finish our work, to shut all of this down,
we need to go there.
These auroras, they come and go in a blink.
We need to go while it's still here.
- Wait!
- Gavin, you can't go anywhere.
- Sam, Ty, hey. What are you doing here?
- Do you have the chip?
- Yeah. How did you know that?
- It's a long story.
We need to get that microchip back to 10,000 B.C.
Eve's life depends on it.
- Gavin, I hate to say this,
but this is bigger than your family.
We have to shut down the project,
and to do that, we have to go to 1965.
- OK, OK, hold on.
I just need some time to think, OK?
[energy pulsating]
- Gavin, the aurora is going away.
There's no time for that.
- Well, then we're gonna make the time.
- Hey. - I'm sorry,
but this is not a negotiation.
.
- Hey, hey, what are you doing?
Hey, put the gun down.
- I'm trying to do the right thing,
and I think you understand that.
- I don't!
- You may not remember, but I'm your sister.
We're family, Gavin, and we trust each other.
So I'm asking you to trust me now.
- She might be your family, but what we've been through,
I'd call us family too.
Deep down, you know I would never lead you astray.
Please, give me the chip and let me bring it back.
- Helena, hey, just give me a minute.
I need a minute to figure this out.
- Gavin.
- If I get you down there, you're gonna do
everything you can to help the people we care for.
- I need to think. - Of course.
[both grunting]
[gunshot] - Oh!
Hey!
[both grunting]
- Sam, stop!
[dramatic music]
- Hey.
- Do not move.
- You're making a mistake.
[energy pulsating]
- Gavin, I made a promise
that I would look out for your family,
and that's what I'm doing right now.
Please, give me the chip.
- Gavin, don't do it.
* *
- I'm sorry.
Go through the blue light.
- I swear, I will make this right.
* *
- Maya. Maya.
Hey, Maya--hey, come on, we've got to get out of here.
- I'm just finishing up.
Where's Gavin and Izzy?
Scott, where are they?
[suspenseful music]
- You've been lying to me.
- What?
* *
- Three scars on your arm.
You said you didn't know why your program was
interested in me,
but you personally had my paper,
gave it to Gavin, which means you must know.
- Scott, I think you're jumping to conclusions.
- By the look on your face, I don't think I am.
What else have you been lying about?
Have you been lying to Gavin too?
Has all this been a ruse?
I'm gonna tell him what's happening.
- No.
You're not going anywhere.
[both coughing]
- I still don't see him.
- He'll catch up. Don't worry.
- Maybe we should go back.
- [coughing]
- Hey. - Maya?
- What happened? - Where's Scott?
- [breathing heavily]
- I tried--
I tried to fight them off, but they took him.
It was the people from the base.
* *
- Lucas?
Sam?
[tense music]
* *
Lucas?
* *
No, no, no, no, no.
No, no, no, no.
[wolf whining]
Wake up.
Lucas.
Lucas, please!
[both coughing]
[soft music]
[wolf whining]
- I'm awake. I'm awake. Hey.
- Don't scare me like that.
- Guessing you got the dam to break.
- Some good aim, a little luck.
The fort's safe too.
- I'm real proud of you.
I'll bet Ruth is too.
- What do you say we go home?
- [coughing]
- Come on.
- Come on, boy.
Come on.
[wolf barks]
* *
[indistinct chatter]
Hey, buddy. Good boy.
- Sam.
- Ty!
- [chuckles]
It is good to see you too, Sam.
- You OK? What happened to you?
- That aurora I went through, it brought me back to 2021.
I've been on quite an adventure.
And...
I got your message.
- I can't believe it worked. - Yeah.
- Ty!
- Look.
- You did it.
- It's a long story, but we did it--
the three of us.
- You know, I could kiss you. [both laugh]
- Well, hold that thought. There's more good news.
Now, to get back here, I went through another double aurora.
I learned they go to two places,
2021 and 1965.
Josh and Riley, they didn't go through the same color light
as I did.
- You think the aurora sent them to '65?
- Yeah.
Yeah, I don't know how to get there yet,
but it's a step in the right direction.
- Thank you, Ty.
All I know is, with this,
we're one step closer to bringing Eve back.
