In a world where humans transform into beasts, a boy outcast from society must carve his own path in the criminal underworld.

Bili is the son of a notorious gangster, but his quiet and lonesome demeanor makes him an easy target for local thugs. When an unexpected beating takes a ruthless turn, Bili is overcome with intense rage and trauma--transforming him into his chimera form--into that of an ape. As he struggles to cope with his new life, he faces ever growing challenges--from confronting his hatred for his father to learning how to thrive in the unforgiving slums ruled by crime lords and corruption. With the aid of new comrades, Hamed a baboon and Zatoichi a blind monkey, Bili embarks on a life of purpose--a life of cold, unapologetic vengeance against each of those who have taken a piece of him--who he once was . . . and what he will ultimately become.
