Kein Mann für zwei(1982)

Jochen Hamann met Martina Schwarz during a stay at a health resort lasting several weeks. The two fell in love and continued their affair after the cure. This is, of course, much to the displeasure of Jochen's wife and Martina's husband. Renate Hamann and Michael Schwarz then form an alliance of convenience, so to speak, in order to separate the two again over time. But this is not as easy as initially thought. In the end, however, Jochen is the one who has to decide who he wants to live with in the future. Either with Renate or with Martina.
