That is, until the day he discovers a mythical golden statue in his mother's art museum that transforms the beholder into a werewolf. Within no time at all, a new world opens up before him. Ace discovers an underground village of werewolves, and learns that he is the only one who can cure them of the werewolf curse. Along the way, he learns that an ancient sorcerer named Melvin Incubar is searching for the statue in order to obtain its legendary power. Now, Ace must find a way to cope with his new life as a werewolf, as well as protect the statue before Incubar can find it and regain his power.
