Between January 1 and December 31, 2017, 768 people died as a result of murder or manslaughter in Britain - approximately 14 people a week. This documentary tells the stories of some of those cases, following victims' families and friends from the immediate aftermath of the crime, through the court process and beyond, as they try to rebuild their lives. The programme also goes beyond individual incidents to ask what the patterns of murder say about the state of modern Britain.
