Shipboard shenanigans as this cartoon opens with a sleeping Jerry aboard a cargo ship taking delivery of items, including some choice cheese. Tom is the cat on watch duty who must keep Jerry from getting to the cheese. He has more problems with the shark in the water who will gulp anything in sight, especially Tom! A mad series of antics ensues, ending with Tom pursued out to sea by the shark and Jerry in a sailor suit, saluting the captain and dancing a jig.
