In this powerful documentary about gun violence, Reggie Yates (Rastamouse, Doctor Who) travels to Chicago to investigate gun crime there. There were 468 murders last year, and in 2016 the murder rate soared by 72%. Most of the victims are young African American men. Over the course of the doc, Reggie hears first-hand the accusations of police brutality, and attends the aftermath of a shooting and the funeral of a young black man. He comes to realise that the majority of killings are perpetrated by young black men living in Chicago's poorest neighbourhoods, and questions what can be done about the violence.
