Inventor Carl Åkerblom is a rosy-cheeked 54 year-old admirer of Franz Schubert - and a patient in the psychiatric ward of Akademiska Hospital in Uppsala, after having attempted to beat to death his fiancée, Pauline Thibault. Together with another patient, Professor Osvald Vogler, they set up a film project: the living talkie. Before long, they set off on a frantic tour with their film, "The Joy of the Joyous Girl"...
