Verdens rigeste pige: One dark night, a ravishing young girl flees from a convent boarding school in Switzerland. She is Lisa Hoffmann, daughter of a wealthy Danish-American oil magnate from Brazil, and she is running away with her sweetheart, the calypso singer Jacque. There is a huge uproar in newspapers around the world, and even more so when it turns out that the two young people are performing in cabarets around Europe's capital cities.
