It usually turns out differently than you think. The entrepreneur's daughter Isabella Meinhardt had to experience this when she returned to Germany after studying for years in distant Japan. Her father Friedrich asked her to come home - and Isabella is convinced that she already knows the reason for this: she should take over the management of the traditional Meinhardt automobile works at his side. The shock is all the greater when she learns the real reason for her visit: In front of the assembled crowd, the widowed Friedrich does not announce his collaboration with his daughter, but his engagement to the public prosecutor Viola Kassen. Isabella, who had no idea of the new woman at her father's side, is stunned. She and her father have always had a very distant relationship, and this time Isabella feels ignored by this in two ways. She wants to leave immediately, disappointed and angry. To prevent a break with his daughter, Friedrich gives in.
