Jake Gyllenhaal headlines this sci-fi time-travel thriller directed by Moon's Duncan Jones from a script by Ben Ripley and Billy Ray. A bomb explodes on a Chicago train, derailing the locomotive and killing hundreds. In an attempt to identify the bomber and prevent another, larger attack on downtown Chicago, Captain Colter Stevens (Gyllenhaal) agrees to take part in a clandestine government experiment dubbed "Source Code," which allows him to enter the body of a male passenger during the eight minutes before the man is killed. But during his first trip back, Capt. Stevens fails to gather enough clues to prevent the second attack. With time quickly running out, he repeats the mission ad nauseam in a desperate race to head off one of the most deadly terrorist attacks ever to take place on American soil.
