In this long-running, hit BBC crime thriller, forensic pathologist Dr. Samantha Ryan helps solve murder cases with harrowing evidence that speaks louder than words. While Cambridge police detectives interview witnesses who may or may not tell the truth, “Sam” extracts revealing truths from calcified bones, decomposed and charred bodies, tell-tale bruises and overlooked fingerprints. Brace yourself for twists and turns in four gripping episodes: the suspicious drowning of a six-year-old girl, the apparently ritual killing of a young man, a death in police custody, and the fiery murder of a refugee’s business partner.
