The film is a vibrant musical comedy in the style of "8 femmes." Set in a guesthouse in a Dutch town run by Sister Klivia, its inhabitants are warm-hearted and upbeat, in contrast to their grumpy neighbor, Boordevool, who tries to shut the guesthouse down. A guesthouse resident meets a nice young man named Gerrit and Sister Klivia lets him stay, despite him being a thief. Will this provide ammunition for the neighbor's complaints?
