stalking another president (Jim Curley) running for re-
election. He has spent long hours studying the psyche of

 When decorated soldier Captain Colter Stevens wakes up in the body of an
unknown man, he discovers he's part of a mission to find the bomber of a Chicago

of a government experiment called the "Source Code," a program that enables him
to cross over into another man's identity in the last eight minutes of his life. With
a second, much larger target threatening to kill millions in downtown Chicago,
Colter re-lives the incident over and over again, gathering clues each time, until
he can solve the mystery of who is behind the bombs and prevent the next attack.
