Berlin at the end of the 1940s. Anneliese Weyher is working as a switchboard operator. She is living with her aunt after losing her parents in the war – a stroke of fate that has thrown the young woman off course emotionally. Indifferently, she is doing her work; her private life consists of an affair with a black-marketeer. Even when Anneliese witnesses an armed robbery, committed by infamous Wollnick and his gang, she stays lethargic and apathetic – she keeps silent instead of helping the inspector who is a friend of her aunt. It is not until Anneliese by coincidence meets her former lover, the watchmaker Kurt, that her life seems to take a positive turn.
