Using Nell's old radio, Pete and Linda are transported back to World War II. As they soon realise, everything they do in 1945 reflects what happens in 2001. Now, Linda and Pete must make life go back to normal or the Gribbles will have complete control of Port Niranda.

Remember the strange person who keeps popping up in the lighthouse? It turns out she is Princess Ariel of the Isle of Dreams, and is looking for more people for her home. She has chosen the Twist and Gribble kids to join her. This leaves Pete, Linda, Bronson, Gribbs, Tiger and Rabbit having to decide whether or not to leave Port Niranda forever. Meanwhile, Fay handcuffs herself to Mr. Gribble and then goes into labour!
