Back in the city that never sleeps, Bennett takes over a chaotic Outreach Squad in Harlem, where he receives an unusual call: a man claims to have seen a group of well-dressed men holding a bizarre party in a condemned building. With no clear crime or evidence, Bennett dismisses the report. But when a charred body is found in that very same building, he is forced to take the caller seriously - and is drawn into an underground criminal world of terrifying depravity.
