La castidad de Britt-Marie, hija de un pastor protestante, le provoca a Satán una verruga en un párpado. Para deshacerse de ella, manda a la Tierra a don Juan para que seduzca a Britt-Marie.
The burglar Karl Kilian Ledig tries to get his somewhat reluctant son Carl Gustaf interested in his "profession". He bring him along one evening to the sculpture Ulla-Carin von Knaake's house to break in and steal from her safe. Complications arise when Ulla-Carin and some of her friends unexpectedly come home and she imagines that Carl Gustaf is a model she has hired from a model agency.
