2007
Military pilot Colter Stevens repeatedly wakes in another man's body on a commuter train, tasked by Captain Colleen Goodwin to identify a bomber before the train explodes, all while his own body remains on life support. Through multiple eight-minute iterations, Colter gathers clues, identifies Derek Frost as the bomber, disarms the bomb, and develops a connection with fellow passenger Christina, whom he attempts to save. After successfully preventing the bombing and Frost's subsequent attack, Colter requests to remain in the Source Code reality for his final eight minutes, sharing a heartfelt moment with Christina and calling his father. Goodwin grants his wish, allowing Colter's consciousness to persist in the Source Code reality, creating a new timeline where he and Christina are alive, and he sends a message back to Goodwin in the original timeline, revealing the program's potential to create new realities.

Colter Stevens, ChristinaThe freight car blows up from the fire. It spews gas, or what could be gas -- it might be chlorine, so they can't take any chances. So they decide to play it safe and evacuate parts of New York City. And maybe that's part of the terrorists' plan, right? So... so who benefits from that? What's vulnerable? What's down there in lower Manhattan? Wall Street.
Steph, it's Christina. You know that story you're always looking to write? I might just have something for you. I met a guy. His name is Colter Stevens. He says he's in the army. He flies helicopters in Iraq, but now they've put him into a secret project called Source Code. Maybe you can look into it a bit, okay? Call me.
So Source Code opens up another past for you. A parallel past. It looks the same but it has no intersection with our own world. In essence, by sending you back, an entirely new but utterly parallel world is created. It looks identical to ours, but nothing you do there has any effect on this reality.
Lower your pulse. The situation has worsened. The fire on the tracks caused one of the freight cars to blow up and release some kind of gas. As a precaution they're having to evacuate all of lower Manhattan.
I resent this. This is harassment. You obviously work for someone. FBI. CIA.
Most of my friends are in the military. My dad runs a melon farm in Alabama.
Then how do I know all those things about you if we've never spoken before?
Wall Street. That's what they're going to hit next. The financial markets.
