After a merchant ship lands on the island, Crusoe and Friday discover that it has been taken control of by a group of mutineers. Crusoe contemplates forming an alliance with the ship's trapped captain in hopes that he can provide him with a means to return to England. Captain Taylor agrees, and they plan to kill the leader of the mutineers, Jacob, so that the rest of the crew will no longer serve him under fear. While planning their attack, they come across the ship's physician's assistant, Oliver, who is actually a woman disguised as a young man. However, she quickly proves that she is more than a match for any man who crosses her.
