When a young frequenter of London's underground club scene is found brutally murdered, detective Alex Taylor is put on the case. Forensic evidence shows traces of a halluciogenic drug in her system, a drug that has previously driven whole tribes mad with the belief that they are being persued by a vicious Werewolf. As Alex is drawn further and further into the club scene, he comes to realise that solving the case will be more complex than he first imagined.
