Jeffrey Baker's got a problem, and his name is Robin Dessart. Robin, the new kid in Jeffrey's class, is a know-it-all and a bully. First, he gives all of Jeffrey's friends a hard time. Then he gives Jeffrey the chicken pox!

Jeffrey knows that the only one who can stop Robin Dessart is Max, the third-grade ghost. Max's endless pranks should put Robin in his place once and for all. And Jeffrey's birthday party is coming up-the perfect day for revenge! But, as usual, Max has a few tricks of his own up his sleeve, and Robin isn't the only one in for a surprise. . . .
