Bryant & May and the Bleeding Heart

Two teenagers who see a dead man rising from his grave. And if that's not alarming enough, one of them is killed in a hit and run accident. Soon it seems death is all around and Bryant and May must confront a group of latter-day bodysnatchers. More graves are desecrated, further deaths occur, and when Bryant is blindfolded and taken to a secret society, he realises that this case is more complex than even he had imagined.
