Dewey has grown indifferent towards his own and others' situation after being bullied for years for the way he talks - he can't help but sing instead of speaking normally. Today is his first day at a new school, and he's already being laughed at by the entire class. However, in a strange turn of events his constant singing causes Biff, the leader of the bullies, to be ridiculed in front of a large group of fellow students. Among the onlookers are the nerds, a trio of other bullying victims, who soon ask Dewey to join them in a rebellion against the bully regime. Their rebellion will prove to be one of song and dance.
