David Jason returns to the role as loveable rogue, Des in the hugely successful comedy drama. In 'The Pilot', trusted by inmates and prison guards alike, Des is a simple, stammering soul who wouldn't hurt a fly. Little do they know, Des has a spring in his step and twinkle in his eye that's worth millions. He's a master of disguise and being in prison is all part of his ingenious plan - Des needs the perfect alibi for the perfect crime. In 'A Royal Affair', Des breaks into the seemingly impenetrable Buckingham Palace to steal a large diamond before it is handed over to the Indian Government. Will Des manage to pull off an elaborate heist before they realise the diamond's a fake? In 'Old School Lies', Des Attempts to relieve a large financial institution of a vast amount of money after they've plundered innocent people's pension funds. Will a shooting accident prevent Des and his accomplices from achieving justice? In 'Old Gold', Des plans to steal £8 million pounds of Russian gold for the families of Russian and British secret agents who have been killed. Despite Des' good intentions, will his wrong doings finally catch up with him?
