A 1939 test pilot asks his best friend to use him as a guinea pig for a cryogenics experiment. Daniel McCormick wants to be frozen for a year so that he doesn't have to watch his love lying in a coma. The next thing Daniel knows is that he's been awoken in 1992.

20 volunteers agree to take part in a seemingly well-paid experiment advertised by the university. It is supposed to be about aggressive behavior in an artificial prison situation. A journalist senses a story behind the ad and smuggles himself in among the test subjects. They are randomly divided into prisoners and guards. What seems like a game at the beginning soon turns into bloody seriousness.
