In the midst of the war of 1812, a British frigate fires upon a peaceful, unwitting mercantile ship. In the attack, the trader's captain is killed and the British take the surviving crew prisoner, including sailor Dan Marvin and the late captain's willful daughter Corunna Dorman . In captivity, Marvin and Corunna form an uneasy alliance and, along with the other prisoners, plot an escape. Their goal: Reclaim their ship and avenge the murder of their captain.
