The terrifying CCTV image of a toddler being led to his death haunts this episode of Law & Order UK which deals with the difficult and morally complex issue of children who kill. As a society, we are very unforgiving of child killers but if the killers themselves are only children, it begs the question - who really is responsible for the crime? With two children in the frame, each blaming the other, can forensic evidence prove who is guilty of strangling little Conor to death? In an emotionally gut wrenching episode, George defies his superiors and instead takes instruction from the victim's mother who has a surprising point of view on the crime. Can the justice system, and ultimately the government, afford to be lenient?

The case starts with the murder of a doctor in the car park of the hospital where she works. What initially seems like a crime of passion soon unravels into a conspiracy involving senior government officials. Risking their careers, James and Alesha must get to the bottom of this case before another life is destroyed.
