Sunset of Power is regarded as one of Buck Jones' more meritorious Universal westerns. The heavy of the piece, grim-visaged cattle baron Neil Brannum, drives everyone around him mercilessly, including his own granddaughter Ruth. In retaliation, a caped-and-masked Spanish bandido stages nightly raids on Brannum's spread.
