Vienna, 1826. The penniless composer Franz Schubert lives with friends in the house of court glazier Tschöll and his wife. Because of their three beautiful daughters, Hederl, Haiderl, and Hannerl, the property is called the "Three Girls' House." Hederl and Haiderl celebrate a double wedding with the gentlemen, master saddler Bruneder and postmaster Binder. Due to an intrigue by soprano Lucia Grisi, Hannerl, with whom Schubert is in love but dares not reveal herself, turns away from him and marries singer Franz von Schober. Schubert is left with nothing but music.
