Was ist bloß mit meinen Männern los? (2002)

Twelve-year-old Fridolin Sternberg (Max Felder) is looking for answers about why his parents divorced. In the process, he meets Boschi online, who wants to grant him a wish. Fridolin wishes that he could be in his father’s place. His wish comes true, and Fridolin switches roles with his father, Dr. Daniel Sternberg (Thomas Heinze). His father now has to go back to school in a child’s body and, with the help of Fridolin’s best friend Katja (Sidonie von Krosigk), manage everyday life. Meanwhile, in his father’s body, Fridolin tries to get rid of his father’s new girlfriend and win his ex-wife back. In his job as a judge, he runs into a number of problems, and also discovers that his mother now has a new lover too (Eric Martin, played by Christian Tramitz). After some of the problems have been resolved, the transformation must also be reversed by a wish from both father and son within 48 hours at the latest; otherwise, the switch will become permanent.
