Helene Sonntag, 40, unmarried and a teacher. She has long dreamed of happy partnership, but things turn out as they should. In order to avoid the work overload caused by substitute teaching and vacation childcare, she is forced to make a move.

"Je oller, je doller", say the roommates of pensioner Otto Panke, because they often see him together with the young Manuela, who likes to invent "dream jobs" for her life and dreams of an "exclusive life". But for Otto, the noticeable sympathy for the pretty, quite professional woman is simply "soul kinship". And since both have an extremely large degree of imagination, they are special, extraordinary - to a certain extent "spider fix"! The problem of the two is that they often get into tricky situations that threaten to get messy and they get a lot of problems. But as is the case with good stories: in the end, everything aims at a happy happy end...

One day, the happily married Karl Lehmann is asked by his single colleague, Mrs. Schmidt, for an unusual service: She wants a child. Lehmann is willing to help. His wife Inge and Mrs. Schmidt have a child at the same time, and since the women like each other, they make an agreement. They share Karl Lehmann. One week Inge gets him, one week Mrs. Schmidt - always alternating. It could be nice if it weren't for the prudish, shocked or even envious people around them. However, some see it in a positive light. A Mr. Schmidt is interested in Inge's week off and a colleague Lehmann is interested in Mrs. Schmidt's week off. And it's not long before Mr. Karl Lehmann is booted out and seeks refuge with a waitress.
