Composer Jørgen Rhoders lives an easy life, at least according to his son Per. Per and his stepsister, Ulla, decide to give their father a little trouble so that his compositions will improve. However, Jørgen deceives the children, and only when the children cause their parents to fall out does the situation seem to improve. Meanwhile, Ulla believes that Per is in love with Lily.
