Harry Wegener (Günther Maria Halmer) has made his dream come true. The successful animal photographer roams jungles and savannas - until a mild heart attack forces him to return to Germany. The world traveler now needs someone to take loving care of him. His younger daughter Fritzi (Claudia Eisinger), a single mother, cannot care for him in her small apartment. There would be enough space in the stately family home, and mother-in-law Sophie (Christine Schorn) would be happy about the return of the life artist, whose cheerful clumsiness would bring some color into the gray everyday life. However, his wife Katharina (Angela Roy) and his daughter Julia (Susanna Simon) have not forgiven the egomaniac for simply running away. For better or for worse, they accommodate the notorious chaotic in the attic in the hope that he doesn't disrupt their everyday life, which is perfectly coordinated with healthy eating and order. Of course, Harry doesn't miss an opportunity to shake up the women's shared apartment: the little tummy that he compliments Julia on is not, as Harry thinks, due to her pregnancy. No fuse box or expensive vase is safe from the clumsy. When the fire brigade has to come because he almost burns down the house at a small party, the limit is reached. Harry is annoying. But in all the chaos, Katharina rediscovers her old feelings. Julia also finally comes out of her shell thanks to her father. But then the unexpected happens.
