Obese Dominick DiNapoli gets a wake-up call when his rotund cousin dies at a young age. He decides that now is the time to shed some pounds, so he joins a weight loss group called Chubby Checkers. But a lack of willpower and an obsession with food prevents Dominick from sticking to any kind of diet; in fact, he often embarks on eating binges to satisfy his ample appetite. Unable to lose weight, Dominick's negative feelings about his body begin to change. As a result, despite the health risks, Dominick begins to accept himself for who he is, not for what he looks like.
