Pierre Winton promises to avenge his father's killing at the hands of McGuirk, the bandit. While hunting for McGuirk, Pierre comes upon Mary Brown who has been badly injured in a rock slide. They fall in love, but while attempting to rescue Mary, Pierre is trapped and rendered unconscious in another rock slide. Saved by Jim Boone's band of outlaws, Pierre joins the gang, and Boone's daughter Jackie falls in love with him, but Pierre still loves Mary, from whom he has been separated. He finally finds her at a dance, and Jackie becomes so jealous that she dashes home, only to find it in ruins, the work of McGuirk. Pierre pursues McGuirk, catches and kills him. Finally, Jackie realizes that she only feels friendship for Pierre, and he and Mary go East to start a new life.—AFI
