The three knight-robbers from the 20th century live together in their medieval castle. For fun, they occasionally organize car races, which are not necessarily about who has the fastest car, but rather who wins the most beautiful woman.

Kathrin Fischer applies for a job as a housekeeper for the wealthy Gisela. But when she turns up for her interview, Gisela seems to be busy with other things. She's doing it with the gardener and her stepdaughter joins her. Kathrin decides to do the same and has fun with the chauffeur Oliver and other staff.
