16 students wake up in a diner dressed in clothes more fitting of the 1950s time period..but from what they can remember, they're from decades past that. Eventually the crackling of the jukebox turns into a haunting yet commanding voice, telling them they all must kill each other to leave the establishment. Dont get caught, and you'd get to go free..making all of your other students perish. Get caught and..its lights out for you.
