Silent Witness is back for its 15th season, promising to be as sexy, cerebral and suspense-filled as ever.
Forensic pathologists Dr. Harry Cunningham (Tom Ward in his final season on the show), Dr. Nikki Alexander (Emilia Fox) and Professor Leo Dalton (William Gaminara) painstakingly examine the bodies of the deceased to search for vital clues that may reveal the cause of death.
Silent Witness continues to explore contemporary issues through clever and thrilling crime mysteries. This time around they must tackle the sex grooming of underage girls, confront a female serial killer, uncover a family annihilation and investigate an exorcism.
The new season sees the addition of an exciting guest cast - including Shelley Conn and Vincent Regan in the opening episode, plus Sanjeev Bhaskar, James Cosmo, Gillian Kearney, Leo Gregory, Adrian Dunbar, and husband and wife Tamzin Outhwaite and Tom Ellis playing alongside each other in episode six.
In the first two-episode story, Death Has No Dominion, Leo is in emotional turmoil when old friend Professor Lizzie Fraser commits suicide. It's a double tragedy as Lizzie's sister, a forensic scientist, was stabbed to death at a crime scene 10 years ago.
After Nikki attends her father's memorial she joins the team at the scene of a violent triple murder at a farmhouse. But soon Detective Superintendent Tom Byrne takes charge.
DNA at the farm matches that of mysterious female serial killer, The Wraith. But Nikki starts to question the investigation after she meets the parents of a murdered policeman.
In Part 2, Harry persuades Detective Inspector Connie James to disobey police orders and secretly test DNA evidence from the original investigation. Leo is still troubled by the suicide of old friend Professor Lizzie Fraser and Nikki learns more about the circumstances surrounding the death of Lizzie's sister.
The strain of the murder investigation becomes too much for Detective Inspector Ginny Gray and the team turn to Janet to help profile the personality of female serial killer The Wraith - but is it enough to catch her?
