Since Moon premiered last year to critical acclaim, movie fans have been anxiously awaiting the sophomore effort of director Duncan Jones. Titled Source Code, the film stars Jake Gyllenhaal as a soldier who is being used as part of an experiment to discover the cause of a recent train accident - and with our review of the script here we told you what to expect. Now the first official image for the film has been revealed along with an official plot synopsis

The plot synopsis fits with our script review. As we said back then, it kind of sounds like Groundhog Day with a sci-fi twist and terrorist bombers - and in no way is that a bad thing.

Check out the official synopsis below and head on over to Collider to see the full new image where it originated.

Captain Colter Stevens (Jake Gyllenhaal) wakes with a jolt to find himself on a commuter train heading into Chicago. Although the other passengers all seem to know him, he has absolutely no idea where—or even who—he is. The last thing Colter remembers is flying a helicopter mission in Iraq, but here he is in someone else’s life going through someone else’s morning commute. Before he can do anything an express train zooms by on the opposite track and a bomb explodes, seemingly killing Colter and all the other passengers.

Colter comes to in an isolation chamber, strapped to a seat, and wearing his military flight suit. He still has no idea what’s happening, except that he’s being spoken to by mission controller Carol Goodwin (Vera Farmiga), who calmly recites a series of memory questions to which Colter is shocked to realize he knows the answers. He learns he’s part of an operation called “Beleaguered Castle,” but before he can progress any further, Goodwin starts up the machinery and suddenly…Colter is back on the train, at exactly the same time he first appeared there, once again speeding through Chicago with the same group of commuters. Colter figures he’s in some kind of simulation exercise, with his task being to find the bomber onboard the train before it goes off again. Living the explosion over and over, Colter must uncover the identity of the bomber, while also figuring out what the alternative universe of “Beleaguered Castle” is. Adding to the puzzle, Colter uses the second chance opportunities to make peace with his father, and to find romance with a fellow passenger on the train.
