The story of Kurt Weill 's relationship with the American popular theatre. During his years in exile on Broadway, the composer of Mack the Knife and The Alabama Song, who personified decadent Berlin, found a new life in New York, creating such standards as September Song and Speak Low. Director Barrie Gavin describes the film as "the history of an artist ... struggling to write music which could have real meaning for the society he had just joined." Weill is remembered by the conductor Maurice Abravanel and the actor Burgess Meredith and there are extracts from several of his works.
