(2005) The Jacket

Amnesiac Gulf War veteran Jack Starks (Adrien Brody) can't explain why he's been found at the scene of a murder. Ordered to a mental hospital, Jack is subjected to Dr. Thomas Becker's (Kris Kristofferson) unusual treatment plan, which involves mysterious injections, sensory deprivation and confinement in a straitjacket. Locked away on his own, Jack discovers he can travel to the future, where he's compelled to help a onetime acquaintance (Keira Knightley) and investigate his own odd fate.
