Here's how the opening goes in Weekenders Adventures of Transformers: Age of Extinction.
[we see earth millions of years ago when dinosaurs roamed the earth, a Cybertronian spaceship descends to earth and uses devices called "Seeds" to extinguish the dinosaur population and the rest of life on earth]
Arctic Site Foreman: Oh, crap. Darcy, you really shouldn't have come.
Darcy Tirrel: Show me.
[the foreman takes Darcy to the site]
Arctic Site Foreman: Corporate was adamant, we keep running. No stopping operations.
[referring to the metal detector and the security guard]
Arctic Site Foreman: No, no, no. You got to go through. No cameras. He's got orders to kill, I don't even think international laws apply up here.
[Darcy goes through the detector]
Darcy Tirrel: We are geologists first. If this thing has any historical significance at all, we are shutting down. I'm shutting us down.
[the guard points his rifle at Darcy as she starts going towards the site, the foreman puts up a hand to stop him from shooting]
Darcy Tirrel: Oh, he's going to shoot me? Shoot me.
Arctic Site Foreman: Hey, now don't kill her.
[Darcy turns and makes her way to the site and the foreman follows her]
Arctic Site Foreman: This is crazy stuff.
[Darcy and the foreman walk up to a dinosaur corpse covered in a strange metal]
Arctic Site Foreman: Crazy crap.
[the foreman uses a hammer to the metal on the dinosaur corpse and turns to Darcy]
Arctic Site Foreman: Well, what do you think?
Darcy Tirrel: I think history is about to change.
[Then we see Kurumi walking]
Kurumi: Hello Athena.
Athena: Kurumi. What a surprise.
Grizzle: You know about the plan.
Dr. Drakken: To get revenge on Tino and his friends, yes.
Darla Dimple: Well, let's hear it.
Grizzle: Okay now here's the plan...
