Silent Witness returns with Season 23, 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.
A body in the concrete pillar of a car park. A downed plane. Scientific research gone wrong. The cases that end up at the Lyell Centre are rarely straightforward.
Initial suspicions are challenged as the evidence mounts, and Nikki and the team must work harder than ever to find the truth.
In the opening episode, the team investigate a downed private jet. Its passengers include the former US Ambassador, Jonathan Kraft.
Nikki calls her partner Matt from the crash scene to break the news – his friend, and former colleague did not survive the accident. Matt is desperate for answers.
When Thomas is called to an apparent suicide of a successful businessman, he finds unexpected connections to the plane crash.
Are they dealing with a coordinated attack?
