Nicht von schlechten Eltern(1993)

The Schefer family is moving from Kiel to Bremen. Wolfgang Schefer is a Captain in the German Navy and the Commander of the Navy base in Bremen. Sybille wants to get back to her old job--she was a teacher before she and Wolfgang had their first child, Felix. There is just one problem: she works at the same school attended by their children: Felix, Henrietta (Jenny), Moritz, and Alexander (Alex).
