Following a training course, the 28-year-old Helga Baumann, a single mother of two children, meets up with her husband Fred again. They had separated a while ago because their ideas of marriage were completely disparate: The conservative Fred advocated the woman′s role of wife and mother, while Helga dreamt about an emancipated partnership between two employed persons. Now, her sister has brought them back together. At first sight, Fred seems to have changed and, once again, Helga cannot resist his advances. But when she meets with difficulties during a fair in Tashkent, Fred yet again proves to be a petty bourgeois by assuring her that they would get along perfectly without her working.

The young architect Hannelore becomes part of the all-male brigade Fröhlich whose members are supposed to build houses at the Strausberger Platz in Berlin. The brigade men drink a lot of beer and are less than thrilled about the new girl. Hanne is the only one who is absolutely delighted with Hannelore. When he starts a drunken fight on May Day, he is arrested and accused of armed robbery. Hannelore immediately convinces the other men in the brigade to help Hanne.

The story of the steel melter Martin Hoff, whose factory delegates him to a drama school, corresponds to the real life of the actor Manfred Krug. Like his (film) hero, Krug works as a steel melter, does artwork, sings and acts, and is sent to drama school. Like his hero, who behaves anarchically and conspicuously, Krug is soon expelled from school.

13-year old Thomas Berndorf, the son of the rich business man Alexander Berndorf, becomes friends with Hannes Wille, whose father works as foreman. They get to know each because Hannes sometimes is allowed to polish Berndorf′s Mercedes 300. They make a bet whose mother is the most beautiful. Hannes assumes that Mrs. Berndorf is only admired for her expensive jewellery. Thus, he suggests that Thomas should steal a collier from his mother. Out of solidarity, he also robs a golden brooch from his mother. At home at the Berndorfs, a severe crisis threatens Thomas′s parents′ "marriage of convenience", and financial hardships are following on the theft.
