Widower Tommy Tyler (John Mills) is a surly sailor who makes his money off of simple con games while raising his plucky daughter, Spring (Hayley Mills). But two things change: Firstly, Tommy decides to act upon the fact that he has a map that could lead to a sunken treasure. Then, newcomer William Ashton (James MacArthur) arrives, and he catches Spring's eye as the group seeks out that fortune and fights off Tommy's old rivals, who also want to get their hands on the loot.
