When the Great War begins, English sportsman Cyril Hammersley is thought to be a slacker because he refuses to join the army for pacifistic reasons. His American fiancée, Doris Mathers, knows that he is not a coward, but she questions his patriotism when Sir John Rizzio intimates that Hammersly may be a German spy.
