Master baker Oskar Lorenz is plagued by a number of worries, because almost every day one of his employees is affected by a different "ailment", making it difficult for the bakery to meet the plan. After all, Lorenz and his team have to ensure that fresh bread rolls and, above all, Berlin country bread can be sold to customers on time every day. And Oskar alone cannot fill all the gaps in the staff. To remedy this situation, Oskar's sister Ilse has come up with something for her brother: a "disease" that is difficult to diagnose. He is now confined to his bed and can no longer fulfill his duties. Ziegler, his deputy, is deeply impressed by the pitiful sight that his otherwise strong master now presents. This seems to be the first ray of hope for Ilse to cure Oskar's coworker and her brother of their "ailments" at the same time.
