Across Britain serious violence is rising. There have been over 80 murders in London in 2018 alone, which includes eight children, under 18. Panorama investigates why young people are losing their lives, by focusing on just one of these murders. 17-year old Rhyhiem Barton grew up on the Brandon Estate in South London, and was killed on the streets there. Filming with his family and friends, the programme looks at the devastation and loss caused by Rhyhiem's death- from their perspective. It explores what might have led to his murder and how the community has responded to try and prevent more of their children being killed.
