The Clifton family and Meera hire a boat to spend the day on the island. Ted Glenn has also gone to the island to fish.

Pat forgets to bring the picnic lunch and the boat gets stuck in the mud. The family decide to make a campfire and toast the marshmallows that Pat brought, and the apples the children found.

Meanwhile Ted catches a large fish. However, when he leaves it to go put the rest of his stuff in the boat, Pat and the others find it and take the fish.

When Ted returns, he follows the footprints and eventually finds the others. Together Ted and Pat are able to get the boat free while Sara cooks the fish.

Pat and the Reverend are accidentally locked in the vestry. While PC Selby and the others chase after Dr Gilbertson to retrieve the vestry key, Pat and Reverend Timms find a way to escape through an underground passage.
