Leading his motorbike gang on an inner-city crime-wave, Smash-and-Grab robber Marcus leaves a trail of chaos as he heists London's top designer jewellery stores. Amassing a small fortune he becomes a rising underworld face with ambitions soaring sky-high - while younger brother, Dee, a street graffiti artist, lashes out at society with his spray-cans, searching for a new way of life. Dee finds it with high-end fashion model Kirsten - but when Marcus strikes a deal with an organised-crime syndicate and expands into new territory, an ultra-violent gangland war erupts with a ruthless rival mob intent on destroying his business and everyone close to it. With Police and Gangsters closing-in on the family, Dee is forced to remember his loyalties at any cost - while amongst the bloodshed Marcus' gang defiantly prepare to take down the largest target of their careers; The Bond Street Kraffs Diamonds vault. Inspired by the real events of London's smash-and-grab gangs and the New Bond Street diamond robbery.
