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.

After Norman fails to convince his father, a wealthy industrialist, with his brilliant business idea in the form of a chain of doughnut shops, the hopeful young entrepreneur is given an old tenement house to help him get started. He infiltrates the building incognito and finds a job as the unpopular houseboy. Norman realizes that all is not well with the quirky residents when he finds a dead Santa Claus from last year in the fireplace.
