Three Swedish girls are at boarding school and a bit bored with their lessons, so they travel to Hamburg to have a few adventures. Lil tries to get her teacher, who is staying with his girlfriend, around and the others have fun in the city's red light district. They want to spend the night with their sister, one of the Swedes, who supposedly works there as a secretary. Soon everything ends in turbulent entanglements...
