The ideas of the film are far more ambitious and interesting than a lot of other films in cinemas and the result is highly enjoyable and smart. Uneven in tone? Sure, but we should be thankful that an original premise concerning parallel realities delivered with imagination and intelligence is on the big screen.
7:45 A.M., a bomb explodes on a commuter train outside Chicago. The bomber informs authorities that it is the start of a campaign of terror with another bomb in downtown Chicago. Transported eight minutes before the explosion, US army helicopter pilot Captain Colter Stevens (Jake Gyllenhaal) finds himself parts of an experimental investigation tasked to constantly relive the event in order to find out who the bomber is.
