Detective Eddie Argo and his new partner Helen Westcott unearth the meaning of the odd equation and realise each victim is being offered a gruesome choice: kill your loved ones, or be killed.

Abandoned by his mother shortly after immigrating to America, Gon is raised by the mafia and grows up to become a cold-blooded hitman.
