War-games champion Udo Berger is finally on holiday.

Travelling to the Costa Brava with his long-ignored girlfriend, Ingeborg, there they meet another vacationing German couple, Charly and Hanna, and a band of shady locals. They have fun, see the sights, relax. Then, late one night, Charly disappears without a trace.

Desperate to solve the mystery, Udo refuses to leave, even after Ingeborg returns home. Increasingly frightened, the situation slips beyond his grasp and Udo suddenly realizes that the consequences of this ‘game’ are much more serious than he ever imagined.
