In his first leading role, Errol Flynn shot to stardom in this swashbuckling adventure about doctor Peter Blood (Flynn), who treats the wrong patient and is forced to work as a slave on Col. Bishop's (Lionel Atwill) Jamaican plantation. Blood joins up with marauding Spanish pirates, saves Bishop's gorgeous niece (Olivia de Havilland) from a French pirate (Basil Rathbone) and is eventually made governor of Jamaica.
