Wolf and Sabine Palfy divorced 10 years ago. Since then, Charlie has lived with her father, and Louise with her mother, with no knowledge of each other. However, they met by chance at a boarding school in Scotland. Initially, they couldn't stand each other, but after some time, they began to investigate their shared roots. Upon realizing their relationship, they devised a plan to reunite their parents by switching places: Charlie would visit her mother pretending to be Louise, and Louise would go to her father pretending to be Charlie.
