Meine Frau Inge und meine Frau Schmidt

Misery loves family.

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.
