The series focuses on the 20-something year old anti-hero Johnny C also known as "NNY" (pronounced 'knee'). He is a deranged serial killer mass murderer and spree killer who interacts with various other characters generally by murdering them. He elaborately kills anyone who even slightly irritates him then drains their blood and paints one of the walls in his house with it. Johnny is also willing to murder "innocent" people who in his twisted mind deserve their fate for some reason or another. The number of Johnny’s victims is in the dozens if not hundreds — or perhaps even thousands. Authorities are unable to capture Johnny and seem unaware of his existence even though his crimes are often witnessed in public and reported by the few who manage to survive.
