Compo is bored. Since Cyril Blamire left for Oswestry, to live with a woman, things have been a bit too calm for him in town. But soon, Clegg brings the solution to all their boredom. A letter from Blamire asking them to welcome home an old fried of his, called Foggy Dewhurst, and help him cope with the sudden changes in his life, after he was more or less forced to retire. Compo and Clegg meet with the new "third man", the war hero Foggy Dewhurst, who because of his peculiar life and his endless wartime stories soon makes his presence noted around town. His military posture, and his "murderous" impulses only get him in a fight with Big Malcolm, and his military precision doesn't seem to be a great help, when the trio tries to carry Foggy's heavy wartime luggage up a hill.
