Predestination

A time travelling agent is trying to disarm a bomb that explodes and burns his face. Someone approaches and helps him to grasp his time travelling device, which then transports him to a hospital in the future. While the agent is recovering from facial reconstruction, it is revealed that he has been trying to prevent the attack of the so-called "Fizzle Bomber" on New York in 1975. After his recovery, he receives his last assignment.
