Ralph Leslie, a recent graduate from medical school, is recovering from typhoid and is bored as can be. Penniless, all he can think about is getting out of the hospital and sailing on the yacht that he has been watching outside his hospital room window. With a few favors from a good friend, Leslie signs up as a member of the crew. Little does he know that on it's maiden voyage as a pleasure cruise, blood will be shed by the innocent and fear will reign supreme until they are able to return to port.
