Blood on the Moon (1948) is an RKO black-and-white "psychological" western directed by Robert Wise with cinematography by Nicholas Musuraca. The film, starring Robert Mitchum, Barbara Bel Geddes, and Robert Preston has many film noir elements. It was shot in California and some of the more scenic shots at Red Rock Crossing, Sedona, Arizona. The picture is based on the novel Gunman's Chance by Luke Short.

Drifter cowboy Jim Garry receives a job offer by mail from smooth-talking Tate Riling. Garry rides into an Indian reservation and finds himself in the middle of a feud between cattle ranchers and homesteaders. Garry doesn't realize that his new boss Riling is a criminal.

Riling intends to swindle naive landowners in an elaborate scheme involving a plan to make sure that cattle owner Lufton and his family don't get grazing land, thereby losing their stock.

At first aligning himself with Riling, Garry finally figures out that his so-called friend is up to no good. He switches loyalty to Lufton and his daughters, leading to a bloody showdown.
