Romantic comedy about a series of mix-ups. Brigitte Kaufmann wants to divorce her husband Jörg who is an engineer and chief executive of an electronics company – and a hopeless pedant. Benno, a former boy friend of Brigitte, has a slightly bizarre idea how they could save their marriage. A piano player, whom Benno has seen in a bar, and who looks exactly like Jörg, is asked to work his charms on Brigitte and to try to dissuade her from divorce while Jörg is on a business trip. Piano player Engel agrees on the plan and acts as Jörg at home with Brigitte as well as in Jörg′s workplace.
