Mr. Howell decides to put on a play, starring Ginger, after she begins to suffer from home-sickness. But trouble begins when Mrs. Howell decides she wants to play the starring role.

Talk about a painful irony: though surrounded by water, the Castaways suddenly discover that their supply of fresh drinking water is running out. When they pool all available drinking water together and decide to ration it, they discover that they will each receive only a few drops per day. Of course, most of the castaways sneak water from the community supply when Gilligan is standing watch, but return it when the Skipper catches them. Just when all seems lost, Gilligan saves the day!

The Castaways overhear the voices of gangsters discussing buried treasure and threatening their lives. The voices turn out to belong to a parrot, who then leads the castaways to the "treasure" .... a box of crackers!
