During the late 60's a government establishment was burnt down and a dodgy scrap clearance firm was called in to clear the site. They find a lump of Uranium on site and smuggle it away and then try to sell it to a foreign government. This was a true story that was turned into a film. There was a film made many years later , But what was it called? Thanks Roy
