On the Berlin subway, university student Cheryl gets off at her stop in the deserted subway station and is pursued by a mysterious, masked man. Rather than attacking her, the man offers her tickets to a free screening at the Metropol, an isolated and recently renovated local cinema. Cheryl talks her friend Kathy into going with her and they skip class to go see the film. At the crowded theater, they meet two preppy college boys, George and Ken, who take an immediate liking to the girls and help them get a can of cola out of the vending machine. The four sit together in the theater.
