Marit Jansen is expecting her third child - not with her partner Jonas Balzer, but with her affair Christian. This is no problem for the two men, who quickly get along after some initial minor rivalries. However, their son Luis feels uneasy, wanting things to be clear above all else. He misses an attitude from his mother: Who does she actually belong to? Clever Selma comes up with an unconventional solution: the girl suggests that they all live under one roof. Christian soon moves into the terraced house with his two daughters. Even though it is cramped, they manage to grow together - especially since the daughters make music together. When Grandma and Jonas' lover Johanna arrive from Cologne for Christmas, the neighbors can only be amazed. An unusual family model is being lived, with everything that goes with it, including the shared joy of the newborn child.
