Zane Grey's Riders of the Purple Sage

Widow Jane Withersteen is being harassed by an unwanted suitor. She is protected when the gunfighter Lassiter shows up. Bern Venters, one of Withersteen's men, tracks a rustled herd into a canyon and shoots a masked rider, who turns out to be a young woman. Beset by guilt for shooting a woman, Venters takes the wounded woman, Bess, to a remote valley to recuperate. Eventually Venters returns to the ranch, only to find that Withersteen's enemies are planning an attack. Withersteen, Venters, and Lassiter escape, but the gang follows them.
