Detective Inspector Geraldine Steel relocates to London to take on another thrilling murder investigation. While Geraldine strikes up a friendship with her new sergeant, the bodies of two black girls are discovered in quick succession in North London. Concerned about a reaction from the local black community, the police are puzzled to learn that two teeth were extracted from both victims after they died. One of the girls worked in a massage parlour and suspicion falls on a client of hers, a known racist. Geraldine is led to the upmarket shops of Bond Street in Central London. She fails to find the killer who is out prowling the streets hunting for his next victim. A young gay man unwittingly goes home with the killer who also takes another girl home to his attic, where he keeps his victims chained up while he shows them his 'collection'. With the death toll mounting, Geraldine has no time to search for her birth mother as she hunts for the elusive killer the papers are calling 'The Dentist'. When she finally discovers the gruesome collection on display in his attic, the killer knows that Geraldine must be his next victim.
