Meet Joe. He's a nice guy out to catch a copycat killer. The one copying himself.
Joe is in control of everything in his simple life, both his day job as a janitor for the police department and his night work. He isn't bothered by the daily news reports of the Christchurch Carver, who, they say, has murdered seven women. Joe knows, though, that the Carver killed only six. He knows that for a fact, and he's determined to find the copycat. He'll punish him for the one, then frame him for the other six. It's the perfect plan because he already knows he can outwit the police.
