Spike is now head of security that's on a ship headed to Hawaii. The captain of the ship gives Spike a whistle to blow, in case of anything suspicious or any intruders get on board. Just by coincidence, Tom and Jerry happen to be on board yet they're not supposed to be. They go all over the ship, into each and every room, and Spike sees them. He whistles and the captain shows up, but no one is found on the ship, relating to Tom and Jerry.
