Mutineers do not clean rooms, and they certainly don't go to bed early because their parents said they should. It is in that room where Tommy's mattress gets involved and takes Tommy and Stella on a wild ride. After a fright-filled flight, the mattress splashes down, of all places, next to a real-life pirate ship. Here, Tommy and Stella are pressed into service and find out what a pirate's life is really about.
