Weihnachten im September.

Christa Seeliger is proud and happy to work as a secretary for the boss of the traditional Hamburg company Hansecker, because his chocolate factory is famous for having invented the smiling chocolate Santa Claus. It would never occur to her that her boss would much rather be cruising the world's oceans than running his company. So she unsuspectingly allows herself to be used for his purposes when Hansecker secretly sells off the company.
