Two brutal murders. No witnesses.

The battered bodies of two young girls are discovered in North London, one shortly after the other. Desperate to avoid hysteria in the community, the police struggle to make a quick arrest before the deranged killer can strike again. Not having any luck, Detective Geraldine Steel, recently transferred to London, is called in to make sense of the grisly murders and the killer's unusual signature: he extracts two teeth from each of his victims. With the death toll mounting, Geraldine is running out of time as she hunts for the elusive killer the papers have dubbed "The Dentist."
