Clemens (Matthias Schweighöfer) has very little time for his kids. He has been working on a big development for the City and the contracts are almost ready to sign. Just a few remaining tenants will have to vacate their apartments and construction can start. When Rolf (Milan Peschel) loses his apartment in the building, he vows vengeance and goes undercover as a male Nanny for Clemens’ kids. His plan is simple: Sabotage. Yet he did not reckon that Clemens’ kids Winnie and Theo would be so well prepared. They have made it a sport to drive any new nanny out of the house immediately. And they know no mercy when it comes to their weapons of choice and Rolf must learn that being a Nanny is far from easy – at least in this family. But while Rolf tries to save his home and neighborhood, he unobviously becomes the savior of an entire family.
