24 Hours in Police Custody

What Lies Beneath (7x6)

Air date: Jun 25, 2018

A man phones police to claim that there are body parts buried in the garden of a house on an estate in Luton and a search team is dispatched, but faces a wall of silence at the scene. Detectives suspect that it is a fantasy but, more worryingly, they may be being deliberately drawn into a long-running and brutal tit-for-tat gang war. Cameras follow every twist and turn of the case as it escalates further when the mother of the original complainant is stabbed in the chest.
