While DI Nicola Tanner investigates the deadly spread of a dangerous new drug, Tom Thorne is handed a case that he doesn’t take too seriously, until a spate of animal killings points to the work of a serial killer. When the two cases come together in a way that neither could have foreseen, both Thorne and Tanner must risk everything to catch two very different killers.
