Duffy

Half-brothers Stefane (James Fox) and Antony (John Alderton) despise their biological father, callous millionaire Charles Calvert (James Mason). Because Charles refuses to share his wealth with his sons, Stefane and Antony ask hip American thrill-seeker Duffy (James Coburn) to help steal the money they believe is their birthright. When Charles decides to move a large portion of his savings from Morocco to France, Duffy has an opportunity to stage a daring burglary attempt at sea.
