Source Code

Army helicopter pilot Colter Stevens (Jake Gyllenhaal), last aware of being on a mission in Afghanistan, wakes up on a commuter train traveling to Chicago. He finds that to others, including his traveling partner Christina Warren (Michelle Monaghan), he appears as a school teacher, Sean Fentress. As he comes to grips with this revelation, the train car explodes, killing everyone aboard and derailing it and a tanker train traveling the other direction.
Stevens regains consciousness inside an unfamiliar cockpit. Through a screen, Air Force Captain Colleen Goodwin (Vera Farmiga) verifies Stevens' identity. She explains Stevens is in the "Source Code", an experimental device created by Dr. Rutledge (Jeffrey Wright) that allows its user to experience the last eight minutes of a person's life within an alternate timeline. Stevens is being asked to use Source Code to discover the location of a bomb aboard the train and identify who detonated it. Goodwin explains that the train explosion occurred that morning, and was a warning by the bomber as a precursor to a larger dirty nuclear device that will be detonated in downtown Chicago. Though Stevens' actions cannot change the past and save the lives aboard the train, identifying the bomber in the alternate timeline will prevent the deaths of millions more in this one.
Stevens enters the Source Code several more times, finding that he is always pulled back out after eight minutes regardless of whether he stayed aboard the train or not, but continues to eliminate suspected passengers as the bomber as well as coming to a relationship with Warren. Within these jumps, he learns that these events occurred two months after an incident while on duty that reportedly killed him. Once he discovers this, he accosts Goodwin for more information. She is forced to explain that the remains of his body are on life-support at the Source Code facility while his mind is hook up to its computer systems, the cockpit a mental projection of his own mind to cope with the experience. Angered to discover this, Stevens makes a deal to complete the mission, in exchange, he demands they terminate his life support after it is completed, to which Dr. Rutledge agrees.
Back in the Source Code, Stevens eventually identifies a young man, Derek Frost (Michael Arden), as the bomber, and the white van which the dirty bomb is mounted in. On his return, his information is successfully used by the military to capture Frost before he can trigger the bomb. Stevens is praised as a hero, but in private, Rutledge tells Goodwin to renege on the deal and instead wipe Stevens' memory to be able to use him the next time there is such an incident. In talking to Goodwin, Stevens realizes that the promise has been violated, and convinces Goodwin to let him return to Source Code once more after which she will disable his life support against Rutledge's orders.
Once back aboard the train, Stevens assures that the bomb is defused and Frost contained to be taken by authorities. He sends an email out, and then calls his estranged father under the guise of a fellow soldier, mending the emotional distance from their past. Finally, he takes Warren aside and prepares to kiss her as his eight minutes run out. As promised, Goodwin disables his life-support. Stevens is surprised to finish the kiss, still aboard the train as Fentress well beyond the eight minutes, and realizes he remains in the alternate timeline. The train arrives safely in Chicago, and he and Warren ditch work to walk together and discuss their future together.
Later that day, the alternate timeline's Goodwin receives the email send by Stevens earlier just as news breaks of Frost's failed bombing attempt. The email explains that Source Code does work, allowing the user to alter the fates in the alternate timelines. Stevens' email ends with him telling Goodwin that when they use their Stevens, to make sure to tell him that "everything is going to be OK".
