Monika, the only daughter of Maximilian and Fränze Holten, becomes engaged to lawyer Thomas Hesse. Her mother is happy because he is a man like Maximilian, her husband. His father-in-law now gives him the delicate task of protecting singer Alexandra Durran from annoying admirers. Theater director Rother behaves particularly conspicuously in this regard.
