Descius Heiss is a French expatriate, and former Devil's Island prisoner, with two passions; driving shrewd bargains in antiques at his Sly Corner Shop, and the care of his Beautiful violin-playing daughter, Margaret. But, his comfortable wealth comes more from being a fence for stolen goods than it does buying-and-selling antiques. His secret is discovered by his shop assistant Archie Fellowes (Kenneth Griffith),a nasty, sniveling young scroat, who keeps blackmailing Heiss until he goes to far. The film ends in a London concert-hall where Margaret is playing the Mendelssohm Violin Concerto.
