Lisa's marriage is all in all quite happy; unfortunately, her husband never listens to her when it comes to buying new things. To change this situation, she fakes a loss of memory and pretends not to know who her husband is. When he calls the young psychiatrist Dr. Spinelski for help, Lisa acts, as if she believes he is her husband; and as part of the therapy, Spinelski makes sure that Lisa gets everything she wants. Finally, Lisa comes to the conclusion that she'd rather have her real husband and so pretends to fall for him, whereupon they start a new life together. I'll remember to try that the next time I'm not allowed to buy some beer.

Bernd Flor, an aging, but still very attractive, actor feels most at home playing the role of the tireless Don Juan in his private life. He's already been married six times and had left all six women, although the marriages were in no way unhappy. On the contrary: he is still on very good terms with all his ex-wives; especially with his first ex-wife, Katharina. Flor also has a grown-up son by her, Lukas, who is becoming increasingly critical of his fathers behavior with every passing year.

It can hardly be said that things are peaceful in the Berlin apartment building where the film's story takes place. There are constant clashes between the residents – and sometimes that's quite literal: for example, when the widow Bock hid some explosives among the bricks, which detonated when the building's thieving doorman lit them in his stove.
