The Royal Hospital Chelsea opens its doors to cameras for the first time for this intimate portrait of the Chelsea Pensioners. The eight-part series meets some of the 300 'Men in Scarlet' at the barracks who, like three centuries of retired soldiers before them, call this Grade I listed building in the heart of London home. Whether being re-united with old comrades, parading in front of the Queen, or debating moves to modernise their quarters, the old boys, whose average age is 83, cope with the changing face of the Royal Hospital Chelsea united.
