Katrin can only dream of a happy family. Because the patchwork constellation with several involuntarily connected families puts their nerves to the test. To kitten the fragile relationship with her 14-year-old daughter Saskia, she has invited all family members to their confirmation. But Saskia has recently moved to her father and his new family, while the son of Katrins new partner Philipp has moved in with them and since then devastated Saskia's room and Katrins life. It is impossible to think of a harmonious everyday life, let alone a peaceful family celebration.
Everything could be so nice between Katrin and Philip, if it were not the love (patchwork) family! Philipp surprises Katrin with a marriage proposal. But the disappointment of her last marriage has not yet been overcome. And promptly, the events turn over. Julia, her ex-husband's new wife, moves in with her unasked and with children. Not only her pointed-tongued ex-mother-in-law Diana, but also Katrin's own mother Renate, come to help. When Philipp takes her by surprise with a spontaneous surprise wedding, Katrin bursts the collar. A marriage now seems a long way off.
Katrin Wiedemann is on the verge of becoming a school principal. All she has to do is give birth to her third child and then she can start immediately after maternity leave. Katrin has no doubt that, as an experienced mother, she can juggle her child and her career. Especially because her husband Philipp has promised to take all of her parental leave. Unfortunately, the school administration has a different opinion and, after the turbulent birth of little Isalie, asks Philipp of all people to take over as headmaster for the time being. In the mistaken belief that he is doing Katrin a favor, he agrees.
