Plot summary

As a spate of brutal homicides spreads across the city, Officer Miller finds himself neck-deep in trouble, trying to deal with something far beyond his comprehension and powers. People say an infernal "Demon Cop" has been terrorising the weak, linking its superhuman strength to a dark secret dating back decades. Either way, someone, or better yet, something, prowls the streets, killing innocents. And with the police station's New Year's Eve party just around the corner, no one is safe from harm, including detectives. But an ancient evil has latched onto the town, demanding blood. Who can stop the Amityville disease?—Nick Riganas
