Cap and Bucky visit Nantucket where they meet a crazy old man who wants to destroy a ship named "Moby Dick" owned by a woman named Molly because it reminds him of having lost his two sons at sea. He makes an ally of the Moby Dick's first mate, but when the man betrays him and attempts to buy the ship from Molly instead of letting the craft rot, the old man hurls a harpoon at him to try and kill him. Cap blocks the harpoon with his shield and pursues the first mate up the mast. During the battle, the man falls to his death on the deck below. Now that the old man's "curse" has been dealt with, Molly's seagoing future looks brighter.
