What is more beautiful and delightful than the Danish summer when it shows its good side? Director Rasmus Strang enjoys it at his country house with his two daughters Ulla and Linda. Ulla, who is the eldest and daughter of Rasmus Strang's first marriage, rules the home with a firm hand and keeps her stepsister Linda isolated in complete obscurity. Linda is not allowed to go out. Linda is not allowed to get new, fancy clothes. Linda is not allowed to go to singing lessons, she has a beautiful singing voice that just needs to be polished a bit. Like a little Cinderella, she lives in the big old house, even her father, who loves her, does not dare to help her, so as not to get into trouble with Ulla.
