Shot in the head during the 1991 Persian Gulf War, American soldier Jack Starks is pronounced dead by army medics moments before miraculously returning to life. One year later, Jack has returned to his native Vermont, where he is arrested for a murder he cannot remember. Found not guilty by reason of insanity, the veteran finds himself in an asylum, where a maniacal doctor puts him on a grueling regimen of experimental drugs, restrains him in a jacket-like device, and locks him away in a body drawer of the basement morgue. The therapy sends the patient on a journey into the future, where he can foresee his death in four days' time. Now, the only question that matters is: Can the woman he meets in the future save him from The Jacket?
