Predestination

In March 1975, an agent stops a bombing of a public building in New York City, but is caught in a gunfight, containing the bomb too late and suffering severe burns. Someone unseen helps him grasp his time-travel device, which he uses to retreat to his employer's facility in 1992. The agent considers his mission a failure because the "Fizzle Bomber," the unidentified serial-bombing fugitive he confronted, remains at large and will carry out his bombing on another day, ultimately killing over ten thousand.
