Benny wins a trip to Hawaii, leading to Top Cat (and the rest of the gang) joining him on his trip by stowing away. Things take a drastic turn as Officer Dibble also ends up aboard the ship, and the discovery of a suitcase containing counterfeit money leads to Top Cat and the gang being thrown into the brig as suspect counterfeiters. However, with Top Cat's assistance, Officer Dibble is able to catch the actual counterfeiter and verify the gang's innocence.
