In the middle of 1942, Britain's Prime Minister Winston Churchill and his bodyguard Detective Inspector Walter Thompson set off on their most dangerous journey yet, braving die fighters of the Luftwaffe in North Africa to get first to Egypt and then on to the Soviet Union. It was die beginning of a year of perilous travels which was to see them constantly at risk from a shootdown or assassination. In almost any piece of film you'll see of Britain's great wartime leader, he is the man in the background anonymous and secret. Until now his critical role in saving the life of Churchill from a series of attacks has been hidden from the wider public. After the war Walter Thompson's censored book told just part of the story. His full memoirs were suppressed even by Churchill himself only now can we recount the number of assassination attempts on Churchill's life. Many foiled by Walter. This thirteen part series, with unique access to these incredible memoirs, reveals for die first time, the story of Walter's life with Winston. Together they travelled thousands of miles on precarious journeys to meet Stalin and Roosevelt and other world leaders. Together they rode with Lawrence of Arabia, dodged German assassins, were nearly shot down by enemy aircraft, lone gunmen, U-boats and IRA hitmen.
