Based on J.M. Barrie's play "The Old Lady Shows Her Medals," about a young Canadian soldier (Gary Cooper) wounded while fighting in World War I. While recovering from his wounds in London, a YMCA worker tells him that a Scottish widow (Beryl Mercer) without a son believes that he is in fact her son. To comfort the widow, the soldier agrees to pretend to be her Scottish son. After fighting with British sailors who make fun of his kilts, he wants to desert, but moved by his mother's patriotism he returns to the war front and is killed in battle. Later the proud Scottish widow receives the medals that her "son" was awarded for bravery. Produced by Louis D. Lighton and Richard Wallace for Paramount Pictures, the film was released on January 25, 1930 in the United States, (Wikipedia)
