Han Whitman's twisted journey continues in what will be an explosive finale. After the Northumberland massacre, Han Whitman has returned to his normal life. But the carnage in Haydon has changed him. He is a haunted man, jaded by those bloody events. That is, until he realises that his original experiment is incomplete. The experiment must continue, but along a different path. One survivor of Haydon teams up with the son of one of Han's victims to hunt Whitman down. As Han continues his experiment, wading into tides of human filth, and finding love in the most surprising of places, in the shadows someone else is watching the proceedings with keen, calculating interest. The detective assigned to the vigilante killings becomes steadily more disillusioned until a chance coincidence leads her onto the killer's trail. The lives of these five individuals will collide with devastating consequences in the dramatic conclusion of the Sinema story.
