It seems like a good thing when Philip (Mathias Freihof), a high-school teacher, bumps into Tanja (Dagmar Manzel), starts a relationship with her, and eventually moves in with her. But Philip has a secret he hasn't even told himself. He attended a transvestite ball and met a man named Matthias (Dirk Kummer) there, with whom he also has been having an affair. He can't bring himself to tell either one about the other one.
