Flynn plays James Durrisdear, the heir to a Scottish title, who gets involved in a rebellion with Bonnie Prince Charlie against the English crown. When the rebellion fails, Flynn heads for the West Indies where he and his partner amass quite a fortune through piracy. Flynn eventually returns to Scotland where he finds that his brother has taken over his title as well as his longtime love. Based on the novel by Robert Louis Stevenson. Flynn's riotous life had put him long past his peak swashbuckling days, as this film unfortunately demonstrates.
