Summer in Germany, anno 1970. Italy is the number one destination. As every year, swarms of Teutonic tourists make their way to the Adriatic Sea. Only Willi Hirsekorn from Castrop-Rauxel has so far no plans to break south. That changes, however, as the bitchy neighbor Mizzi Buntje proudly tells of their upcoming holiday in Italy. Willi can not afford this boasting. Shortly determined, the bags are packed, and already rushes Willi in the car with his wife Sieglinde, daughter Lotti and son Kuno the sun.

Based on a book by Eric Malpass and directed by Kurt Hoffmann, the film focuses on the everyday life of a German family perceived through the eyes of its youngest member — six-year-old Gaylord.

Captain Ebbs is an older, experienced seaman who has, however, only sailed on freighters. While his current old barge, the Martin Luther, has to go into the shipyard for an overhaul, the shipping company gives him command of the elegant cruise ship Julia to temporarily replace a colleague who has fallen ill. The rough Ebbs finds his way into his new job only with difficulty and initially puts his foot in his social mouth.
