Charlie dispatched by the wild horse Stampede however.—Robert

Young rancher Jack Tanner, who is in love with Jessie Hayden, offers to corral a herd of wild horses that have been spoiling the neighboring cattle ranges, stopping Champion, who wants to shoot them. Meanwhile, a strange woman (Grace Connor?) meets Jack on the range, and he gives her shelter while he searches futilely for the herd; at length, his horse Scout and dog Bunk corral the horses. Jack wants to propose to Jessie, but when she sees the strange woman, she spurns him and goes to Champion, whose proposal she has rejected; and Champion's men set out to steal the herd. While she and Champion ride to town in a buckboard, the herd is freed and begins to stampede, and Jack, learning that the strange woman is Champion's wife, rides after the endangered buckboard; Champion is flung from the wagon and killed, and Jessie is rescued by Jack. A posse arrests the gang, and the lovers are reunited.—AFI Catalog
