Harry Cunningham investigates the death of a young Orthodox Jew. He accedes to the family's request that he not use invasive procedures in his examination and finds that the young man was savagely kicked and beaten to death. DI McKenzie has a suspect in custody but from what medical and forensic evidence Harry is able to find, with Nikki Alexander's assistance, it's obvious that the family is lying about the young man's whereabouts the night he was killed. Leo Dalton meanwhile investigates the death of a young student who died from a drug overdose. Leo is uncomfortable with what he finds, particularly that she had sex with one of the men at a party when her boyfriend was in the next room. He thinks she may have been given GHB.

Nikki y el equipo empiezan a armar una imagen de lo que sucedió, pero no obtienen mucho de ello. Jack acude en ayuda de un viejo amigo y se ve envuelto en un caso difícil.

El CID local encuentra discrepancias dentro de las filas a medida que las pruebas se acumulan contra el oficial de policía acusado.
