George and Harold (the co-stars of the enormously popular Captain Underpants series) are in big trouble again!

George and Harold have created a new breed of justice - one that is part dog, part man, and ALL HERO! With the head of a dog and the body of a human, this heroic hound digs into deception, claws after crooks, rolls over robbers, and scampers after squirrels. Will he be able to resist the call of the wild to answer the call of duty?
