Baldur Justesen is the owner of an ice cream parlor in a Copenhagen suburb. He is a smooth and unassuming man who works hard to keep it running. It is not quite that easy. He has a beautiful, young wife, Sonja, who likes to dress nicely. A man who works all day in an ice cream parlor can also need some diversion, and it is Baldur Justesen's greatest joy to sing in the choir of the "Lyren" singing association.
