Season 21
Silent Witness returns with Season 21, following a team of forensic pathologists helping police solve murders using clues found on the bodies of the victims - the silent witnesses.
Emilia Fox, Richard Lintern, David Caves and Liz Carr return as the dynamic Lyell unit, for five new topical, thrilling two-part contemporary stories set against the familiar landscapes of London.
Moment of Surrender (Episodes 1 and 2)
When Nikki's pathologist friend Sally Vaughn disappears, suspicion falls on her colleague, David Cannon, who is invited to work at the Lyell while police investigate Sally's disappearance.
Nikki is tasked with keeping close watch over his movements as his behaviour becomes increasingly erratic.
Duty of Candour (Episodes 3 and 4)
A series of tragic events are linked to the hacking of a hospital database and the subsequent blackmailing of patients in return for silence over their guilty secrets.
A Special Relationship (Episodes 5 and 6)
A US Diplomat is shot dead in a central London square, forcing Nikki, Jack, Clarissa and Thomas to work closely with the Embassy and the FBI to overcome jurisdictional hurdles.
One Day (Episodes 7 and 8)
A road traffic accident leads to the Lyell team uncovering a large number of abuse cases in a group of homes providing assisted living to those with disabilities. The team - Clarissa in particular - has to fight not only for justice but against prejudice and discrimination.
Family (Episodes 9 and 10)
It's Christmas morning and Nikki, Jack, Thomas and Clarissa are just settling down for their respective festive celebrations when they are interrupted by a call-out to a family home - and the horrific aftermath of a shooting spree.
Silent Witness is produced by Kiaran Murray-Smith and executive produced by Richard Stokes (Silk, Broadchurch) for BBC Studios.
