SPOILERS AHEAD: Plot: 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....says THIS write up at Worst Previews, which goes into quite a bit more detail about what we can expect from Mr. Jones' newest cinematic tale - due in theaters April 2011.
