The radio reports that Mr. Howell has been rescued and is spending all of his money. Obviously, there is an imposter! The real Mr. Howell is frantic, and offers a reward to the person who can come up with a plan to get him back to civilization. Meanwhile, the imposter falls off a luxury liner and ends up stranded on (you guessed it!) Gilligan's Island. There the imposter conks Mr. Howell on the head with a coconut, changes clothes with him, and attempts to continue his masquerade as the millionaire.
