Here's how the highway chase and Optimus and Galvatron's battle goes in Brian and the Eeveelution Family's Adventures of Transformers: Age of Extinction. And also how Lockdown gets Optimus and Tessa.
Attinger: This is our chance. We have to stop him. You have to stop him.
Joshua: It's never been tested on the field. Labs, military bases, but not on civilian streets.
Attinger: Down there a Defense Department contract was just attacked in a terrorist attack. This is now a CIA military op. Your indemnified. Respond!
Gill: Let's go.
[In a control room]
Attinger: KSI Chicago, closest live sat, patch it in. Been an unprovoked Autobot attack.
Joyce: Bring up Galvatron.
Man: Transforming Galvatron.
Woman: [speaking on radio] Galvatron coming online.
Man: Bring up Stinger.
Woman: [speaking on radio] Stinger coming online.
[Galvatron and Stinger are now driving away]
Joshua: Let's show these alien terrorists what an upgrade looks like.
Air force operator 1: Galvatron and Stinger are moving to intercept targets.
[Galvatron and Stinger are moving fast]
Air force operator 2: Reapers, five targets in the open. Good picture.
[We see the Autobots on the screen]
Man: Two miles on intercept.
[We see Galvatron chasing the Autobots and our heroes]
Sunil Nevla: [looks back] Uh, guys? We got company!
Belle: Oh, for the love of pete!
Standing air force operator: 200 miters. Engage. Transform.
[When Galvatron transformed he slammed a truck]
[Next Galvatron splits a car and destroys another one]
Joshua: We are programming this, right?
Man: Yes. Mostly.
Adagio Dazzle: What do you mean, "mostly"?
Air force 3: Systems seem to have malfunctioned.
Man: Targeting five bogeys. Engaging rockets. Missiles away.
Galvatron: [fires missiles but he missies and some of the Autobots and our heroes go another way]
Cade: Gotta haul butts, Bee! Come on!
[Stinger chases our heroes]
Man: Stinger is in pursuit.
[Stinger fires rockest and Galvatron does os to]
Man: Missfire, missfire, missfire, missfire!
Man 2: Systems failure. Galvatron just fired 4 rockets.
Shane: Whoa! They're shooting at us!
Duck: WE'RE GONNA DIE!!!
[Then, the missiles hit a truck, and cause it's trailer to jack-knife]
Cade and Shane: [yelling]
Brian and the guys: [screaming]
Zoe Trent: [screaming]
[Optimus and Bumblebee transform and jump.]
[Optimus catches Tessa, while Bee gets Cade, Shane, and our heroes. Optimus slams in a truck trailer and catches Cade, Shane, and our heroes. Bumblebee hangs down fires rockets at Galvatron but Galvatron avoids them]
Bumblebee: What was that?
Man: We need a full medical team now. Possible civilian causalities.
Joshua: I mean, you got a lot of people in the crossfire here, I don't like.....
Attinger: You're making history here. For your country, for the world. Human freedom is at stake. Innocent people die all the time.
[Back at the highway]
Cade: Come on, Optimus!
[Galvatron fires rockets]
[Cade and Shane jump out as Optimus transforms and hits his foot in front of a car with his foot]
Glaceon: Man, I hate it when they do that!
[Then, Optimus deploys his face mask]
[Optimus and Galvatron start they're fight]
Joshua: Make him fight. Don't let him go down. Make him fight!
Shane: Come on, come on, come on.
Cade: Tessa! Tessa! Tessa, run to the field!
[When she runs to the field Optimus and Galvatron are still fighting]
Optimus: You have no soul! [stabs Galvatron]
Galvatron: That is why I have no fear! You die! [throws Optimus]
[Optimus and Galvatron are fighting on the road again]
Tessa: Help me!
[However, a mysterious rocket comes out of nowhere and goes throughout Optimus!]
[Cade and Shane hide as everyone gasps in horror as Lockdown comes up]
Darcy: What is that?
Attinger: That's my asset. Pull Galvatron back.
Joyce: Do it.
[Back at the chaos, Lockdown's face turns into a high-powered sniper rifle and fires at Optimus which wounds him as Galvatron leaves, Lockdown comes closer]
Eevee: Blythe. Quick, question. Who is that?
Blythe: You're asking me? I'm not Transformer expert!
Cade: I got to go get her.
[Tessa hides in the car]
Shane: [tackles him] Don't go out there, he'll kill you!
Cade: She needs my help!
Shane: She's hidden!
Tessa: Optimus, Optimus, get up, get up!
Optimus: I can't. Get out of here.
Lockdown: I feel sorry for you, Prime. Your allegiance these humans. The trouble with loyalty to a cause is; that cause, will always betray you.
Optimus: Who send you here?
Lockdown: Where did you think you came from? [scoffs] You think you were born? No. You were built. And your creators want you back. We all work for someone.
[A ship comes out and drops a net and captures Optimus and Tessa]
Shane: It's got her! She's in the car!
Peter: Come on!
[The ship gets ready to fly]
Cade: Tessa, get out! Get out! Tessa! [bangs the glass] Get out! Tessa!
Tessa: Dad, help me! Help me, help me, dad, dad!
Cade: [jumps and grabs on the net]
Tessa: Dad! Dad!
Cade: Tessa! Break the glass! Break the glass to get out!
Tessa: I'm trying! Dad!
Cade: Tessa, I can't hold on! Tessa! Just break the glass!
Tessa: Help me!
Cade: Tess... [lets go]
Brian: Optimus, Optimus! No! No! [he's hold back by Sylveon]
Sylveon: Brian, it's too late! He's gone!
Optimus: Cade, Brian, warn the Autobots!
Tessa: Dad, help me! Don't leave me!
Cade: No! [punches the ground]
Brian: No! [holds back some tears] No! [gets on his knees] Why Optimus, why Optimus! [slams his fist on the ground]
[Shane arrives while they both grieve]
