As described in a film magazine,[3] Jefferson Todd (Mayo) and Louis Castiga (Harris), brothers-in-law, come to blows on a Mississippi River steamer when Todd discovers Castiga's presence there with a woman usurping the place of his wife, Todd's sister. Todd, a Southern gentleman whose fortune was depleted during the Civil War, is attempting to rebuild it by gambling on the river boats that frequent the great river. He wins four race horses at poker with Colonel Brereton (Fenton), but refuses to collect the stakes. Brereton insists, and then takes his own life. Brereton's suicide causes Todd to question his new profession. Todd and Castiga again meet at the plantation home of the Colonel's daughter Barbara (Burnham), both having gone there to break the news of her father's death. Castiga's wiliness makes Barbara believe that Todd is an intruder and the cause of her father's ruin. The trouble between the men results in a duel in which Castiga cheats and is driven out of town. Barbara's faith in Todd is established and together they join the great army of homesteaders and go West for the great land lottery that followed the Civil War. They win a race for a homestead involving prairie schooners, buckboards, horse teams, and race horses, but fall victims to a plot hatched by Castiga. In a struggle between the two, Todd is victorious while his enemy meets his death. Love beckens for Todd and Barbara.
