System ohne Schatten (1983)

Forty-year-old Victor Faber lives in West Berlin and works in information technology. He develops and monitors computer programs for corporations and banks. He leads a secluded life in a solitude of his own choosing. He occasionally goes to the theater or to exhibitions, but only with his longtime girlfriend, Renate. At an art gallery opening, Faber and the actress Juliet meet. Juliet has come with her boyfriend, Melo. Melo expresses an intense interest in Faber’s specialist knowledge of computer programs. A few days after the opening, Faber receives an invitation from Juliet to dinner. A love affair develops between the two protagonists. In parallel, Melo pursues an idea: using a manipulation of the banking system to have the daily discrepancies caused by rounding transferred to a Swiss account. After initially hesitating, Faber agrees to the scheme and opens an account in Zurich. The manipulation requires a break-in at the bank, organized by Melo. Only after that can Faber act. But the burglars shoot a security guard, and events take an unforeseen turn.
