Shelby loves to argue and always has to have the final word - at least that's what her boyfriend, Tom, says when he breaks up with her. When Shelby goes to summer camp, she begins to think that Tom may be right: everything she says gets her in trouble.

Then Shelby meets Matthew. He's cute and smart, and Shelby knows he's the perfect boy for her. But when she's up against him in a camp debate contest, Shelby's worried. Will having the last word mean the end of a relationship once again?
