Heathcliff is enjoying a day at the pier when he is taken aboard a ship by a hook. The captain tells Heathcliff that he must get rid of all the rats on board. Heathcliff is dropped in the hold and finds the rat family. He makes a deal with the rats and they turn the tables on the captain. Heathcliff acts like he's chasing the rats and is caught in the act by the captain but Heathcliff pulls a fast one and has the captain going overboard. Heathcliff puts out a rowboat for the captain to use to escape the shark and sails back to port with the ship of rats.
