From Executive Producer Guy Ritchie and Academy Award and Emmy-winning producers, Lightbox, comes a three-part documentary true crime caper. It's summer 2000. A group of South-East London criminals are orchestrating what just might be the most audacious heist of all time. Their plan: use a bulldozer to ram-raid the brand new Millennium Dome in broad daylight, steal the world's second biggest flawless diamond in a haul worth £350 million, and escape by speedboat down the Thames. There's just one tiny problem: the Flying Squad are watching.
