Liza, Eddie, Melody, and Howie (the Bailey School kids) go to camp in the summer before third grade. The camp counselor, Mr. Jenkins, eats raw meat and is very hairy! The children become suspicious when he tells the legend of the lone wolf, has wolf books in his cabin, and wears dog tags. He must be a werewolf! They find out that wolfsbane and mistletoe are cures for werewolves. They find some plants in the woods and take them on a scary night hike where strange things happen. The kids are glad to be going home the next day, but will the werewolf let them leave???
