An unbalanced man finds himself drawn into a web of intrigue and violence in this thriller from director Michael Glawogger. Ratz (Helmut Koepping) grew up with a passionate hatred of his father and a inappropriate attraction to his sister; now grown to adulthood, Ratz is trying to work out his anger for his dad by designing a new video game in which players chase a father figure through an old house and finally do him in. As Ratz travels to the United States to sell his game to an electronics firm, he meets up with a childhood friend, Mimi (Sabine Timoteo), who has grown into a very sexy woman. Mimi needs some repairs done on her house in New York, and she persuades Ratz to do some of the work; Ratz becomes acquainted with Mimi's tenant, Lukas (Itzhak Finzi), an elderly man with a secret, and in time Ratz's story becomes linked with that of Jonas Shtrom (Ulrich Tukur), a man trying to find the war criminals who killed his parents during the holocaust.
