This first programme looks at the Cinderella of the British Motor Industry - Leyland's Truck and Bus Group. It has always made a profit but over the years most of it has been handed back to the ailing car division. Then the Ryder report made the Truck Group a profit centre and Ron Ellis, the Manager of Truck and Bus, can move into battle in Europe with some of our best young engineers. The Risk Business lifts the covers on Ron Ellis's biggest gamble, the still-secret plans for the truck he hopes to launch in 1978.
