In this romantic maritime adventure, Errol Flynn does swashbuckling to a "T" playing Scottish nobleman Jamie Durie, who rebels against his king but is forced to hide out on the open sea with his Irish partner-in-crime (Roger Livesey) when he fails to oust the ruler. Jamie doesn't stay away for long, though -- his sights are set not only on revenge but also on winning the heart of the beautiful Lady Alison (Beatrice Campbell).
