For this year's Pay It Forward Day, George and his friends volunteer to help serve dinner to homeless families. But when George finds out that his favorite movie star will be in town on the same day, he's torn. Should he keep his promise to the shelter, or miss the chance to meet his action star hero? On top of everything, George suspects that his nemesis, Louie, has been reading his private journal. Can George figure out a plan, get back at Louie, and avoid the burp all in one day?
