Jack and Charlie investigate an assault on the owner of the Green Pit nightclub in east London and discover the victim's sister unconscious in the cellar, with blood pouring from a head wound. The detectives' efforts to piece together what happened are hampered by the lack of CCTV footage, and the case takes a confusing turn when a 19-year-old student is found dead with a flyer for the club in his pocket.
Set in London, each episode is a self-contained story, starting with a news report, then following the team of three detectives as they investigate the circumstances the crime. The cases themselves are hard-hitting with contemporary themes, such as the search for a soldier with PTSD, a cuddle that has been made to look like an assisted sleeping and the gang rape of a young teenager.
