Blood on the Moon 1948
Directed by Robert Wise
Mitchum plays drifter cowboy Jim Garry. After receiving a job-offer letter from smooth-talking Tate Riling (Preston), Garry rides into an Indian reservation and finds himself in the middle of a feud between cattle ranchers and homesteaders. What Garry doesn't realize is that Riling, the man he now works for, is crooked.
