To avoid the rest of a boring school outing with the Colonel, Dennis and his friends take a canoe out onto Beanotown Lake. They are followed by Walter, Bertie and Dudley, and the two groups of friends find themselves marooned on a desert island. As on land, the two groups maintain their factions.

At first, they enjoy their new-found freedom, but tensions between the two groups grow when Walter steals Curly's chocolate bar, and as their war is about to escalate, Pie Face seems to lose his mind. Pie Face pursues the pie that he smells, followed closely by Dennis, Gnasher and Curly. When they run through the fog, they can't believe what they see. They never left Beanotown Park.
