Renate travels after him and in the 'Kongo-Express' gets to know the German emigrant Viktor, who has been living in the wilderness for years and is immediately on fire for the young woman. But although Renate is very attracted to the charming man, all she thinks about is Gaston, whom she eventually finds. A short time later, Viktor joins them. There are many jealous fights between Gaston and Viktor, of which Renate is the cause, as the latter is about to leave for Germany...
