A group of Canadian Royal Mounted Police officers arrive home after serving overseas with the Allied Army. After enjoying a birthday banquet for the aged Major Manners amid much singing and revelry, Inspector Turner reveals suspicions about a new recruit, John Smith, whom he knows to be using a pseudonym and whose war record contains something potentially damaging. Smith is purported to have been a flyer during the war; he and his brother fell in love with the same girl who turned out to be a spy and to whom one of them revealed British Air Force secrets, which caused a squadron of planes to be attacked. John meets Freil, another Mountie, who gives him an encouraging talk about self-respect and unselfishness and promises never to dredge up the former's past record. Alice, Freil's daughter, returns home by canoe after visiting her ailing former nurse.
