The Panther is a stowaway on the S.S. Luxitania, where he must hide from a suspicious Big Nose waiter. But the traveling opera singer and the ship’s captain don’t suspect a thing. The short, pointy-nosed steward, assigned to cater to the singer’s comfort, discovers the stowaway Pink Panther and endeavors to catch the unwelcome passenger, only to repeatedly disturb the ship’s captain, who violently punishes the steward. A troublesome deck chair begins to snap its foot rest as though it were a dog, and chases the Pink Panther and the steward off the ship and onto a tropical island.
