First on the scene after an RAF helicopter crashes into a detention center for asylum seekers, forensic pathologists Dr. Harry Cunningham (Tom Ward) and Dr. Nikki Alexander (Emilia Fox) detect a cover-up at the Ministry of Defense. How can you believe in justice when young boys die in ritual killings, the patients of a prominent surgeon have an unusually high fatality rate, victims are murdered despite police protection, and the person you think will help you solve a murder wants to kill you? A dedicated team pulls the truth from human remains in five new, two-part episodes of the BBC's long-running London crime drama.
