A neighbouring farmer's daughter, Annie, and her brother, Martin, the Tremayne's chauffeur, were the only two who would befriend him. But when war breaks out in 1914, Perys' life picks up - his determination and talent for flying enables him to join the RFC and become a distinguished flying ace. Although his war years and flying career go well, his love life was less successful. He is deeply attracted to Annie, but she has an understanding with Jimmy who returns from the Front blind and gas poisoned so she feels she must go through with her marriage.

When war ends, Perys meets up again with Annie just after Jimmy committs suicide, unable to live a disabled life...
