It’s Mikey’s first year at Camp White Lake. He is joined by a group of boys his brother, Matt’s age. Mikey is hoping he can stop wetting the bed this summer, as he feels embarrassed by the GoodNites his mother packed into his sleeping bag. Meanwhile, Matt has discovered that his friends at camp have hit puberty this summer. He has yet to see any changes in himself so far and he worries that he will be a kid forever. Can Mikey beat bedwetting? Will Matt catch up to the other boys?
