Marie Herbst (Christiane Hörbiger) can hardly believe her eyes when surveyors a timeout with tape measures and notepads to measure the beautiful Viennese coffee-house she has been running for several years in the centre of Berlin. It turns out that behind her back Marie's ex-husband has terminated the lease -- in return for a considerable sum of money - another premises belonged to an investment company called Prospecta. A chain of coffee shops plans to take over the desirable premises and is prepared to pay a much higher rent. But Marie refuses to be defeated so easily.

Gerd Fürst is prone to claustrophobia and promptly begins to hyperventilate. Though she has no idea who she is dealing with, Marie manages to calm down the panic-stricken manager.

But when Gerd Fürst discovers who he has been spending a romantic evening with, he feels that he has been the victim of a plot...
