Cap and Bucky visit Nantucket where they meet a crazy old man who wants to destroy a ship named "Moby Dick" because it reminds him of losing his two sons at sea. He makes an ally of the ship’s first mate, but when the man betrays him and tries 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 chases the first mate up the mast. During the fight, the man falls to his death on the deck below. Now that the old man's "curse" is broken, Molly's seagoing future looks brighter.
