San Agustin Plains

In New Mexico Territory of the 1880s, Allyson Clayton is sent East to attend school against her wishes. The U.S. Marshal with a prisoner in custody is forced to accompany Allyson and her aunt in the stagecoach. Outlaws waylay the coach to rescue the prisoner, Morgan Coeur, who has been flirting with Allyson. When he invites her to join him, she accepts. Quickly learning she has made a mistake, Allyson strives to protect herself in the outlaws' lair where Morgan has left her. He returns and she asks him to take her home. When he does, she discovers a long-standing enmity between Morgan and her brother, Hect, stemming from a land dispute between their fathers. Hect credits Allyson's seduction as another act of revenge on Morgan's part, but their love is true and guides her attempts to clear Morgan's name and reclaim what has been lost.
