Harry Cunningham es solicitado para revisar un caso en una disputa de seguros. La compañía de seguros se niega a pagar una póliza cuando los resultados de la autopsia muestran que la mujer estaba intoxicada y probablemente fue responsable de la caída que la mató. Su familia insiste en que eso es imposible ya que ella era abstemia. Nikki Alexander investiga cuando se encuentran restos humanos enterrados en un campo. Los lugareños creen que el cuerpo es el de Clara Young, quien había desaparecido 18 meses antes. Los restos se encuentran en el sitio de un campamento de viajeros o gitanos y la policía está convencida de que George Wood, uno de los residentes del campamento, es responsable, pero las pruebas de Nikki demuestran lo contrario.

George Wood es liberado por la policía pero pronto es encontrado muerto en su caravana. Aunque se intenta hacer parecer un suicidio, está claro que es un asesinato. El caso se vuelve aún más complicado para Nikki y las autoridades cuando ella determina que hay restos de dos víctimas en el campo, no solo una. Las pruebas en el asesinato de George Wood apuntan a alguien con conexiones con la policía. Harry Cunningham cree que la mujer muerta en su caso de seguro probablemente sufría de demencia y busca probar la causa.

As Leo's replacement Thomas Chamberlain arrives Nikki investigates the murders of Rachel Freedman, shot in the head, and her little autistic son Nathan, who was poisoned. Nikki rejects policewoman Anne Burchett's theory that Rachel killed them both but is perturbed when an impostor, claiming to be Rachel's sister, visits the morgue. At the same time the disfigured corpse of Eva Liron is discovered, killed with the same poison as Nathan. She had been the nanny to French hot shot footballer Isaac Dreyfus and was planning to blackmail him over a sex tape of them both. Jewish Isaac is a controversial figure due to his anti-Muslim sentiments but he denies ant part in the murders. Then another victim, Isaac's agent Mousa, is discovered dead.

Isaac is arrested but club bosses deny knowledge of the sex tape whilst Rachel's widower Adam tells the police that Eva Liron had been Nathan's nanny but had left suddenly. With Mousa shot by the same gun as Rachel ambitious Inspector Leighton assumes that he was delivering the blackmail hush money and was killed by Isaac, whom he wants to nail, though the pathologists will not assist in any stitch-up. Then Clarissa discovers that Adam and Isaac both donated money to Israel and the motive appears to be that they were targeted by anti-Zionist terrorists after Eva had picked them out. But who is the mystery woman posing as Rachel's sister and who perpetrated the murders? The pathologists assist the police in finding out.
