Henning Heers

Francois Korb is an arms manufacturer who sold both to the Germans and the Allied forces. Korb's home life is less than ideal, since his wife is having an affair with his brother, and his young son is inseparable from a teddy bear. To remedy the son's situation, the parents take in a little refugee girl as a temporary companion and playmate, and the two children become fast friends.

With rumbling stomachs and no engagement, musicians Pit, Max, Bill, Gus, Eddi, and Giorgio are on their way to visit their Uncle Hermann, who runs a sports school on Lake Wörthersee. Along the way, they meet the charming teenagers Susi, Evi, Sieglinde, Inez, and Francis, who are on their way to a girls' boarding school. A strict boarding school where male visits are, of course, frowned upon. So the musicians dress up in drag and visit their friends disguised as 'aunts and cousins.' And, as expected, things soon go haywire.
