The Rainbow Trail(1918)

Following in his dad's footsteps, Shefford devotes himself to freeing his community from the grip of a particularly despotic Mormon sect. In so doing, he rescues his foster sister Fay Larkin, who is coveted by lecherous Mormon elder Wagoner. As was the case in Riders of the Purple Sage, the Mormons are villains simply because they are Mormons.
