On October 2, 1988, troubled teenager Donald "Donnie" Darko sleepwalks outside, led by a mysterious voice. Once outside, he meets a figure in a monstrous rabbit costume named Frank who tells Donnie that the world will end in precisely 28 days, 6 hours, 42 minutes and 12 seconds. Donnie wakes up the next morning on the green of a local golf course and returns home to discover a jet engine has crashed into his bedroom. His older sister Elizabeth tells him the FAA investigators do not know its origin.
