Twilight in the Sierras  Ricardo Chavez is a convicted counterfeiter, who after serving time in a California prison, is released on parole to work on a ranch as he begins his new law-abiding life. The reformed criminal, however, is soon abducted by a gang of outlaws and blackmailed to engrave printing plates to make counterfeit currency for Matt Brunner. Brunner is secretly the gang's leader but presents himself in public as only the owner of a Morongo Valley hunting lodge. Although Ricardo now wants to pursue an honest life and forget his criminal past, Brunner threatens to harm or kill his sister Lola if he refuses to do the illegal work. Roy Rogers is Ricardo's parole officer; and with the help of Pat Callahan, a female deputy sheriff (Dale Evans), Roy uncovers the counterfeiting operation while clearing himself of a false murder charge, saves Ricardo and Lola, and defeats the gang. Reviewers in 1950 generally found "Twilight in the Sierras" predictable but entertaining, especially for Republic Picture's targeted younger or "juve" (juvenile) audiences. "Variety" commented about such targeting as part of its own assessment of the production: Another widely read trade paper in 1950, "Motion Picture Daily", echoed "Variety"’s comments regarding the standardized appeal of Rogers' films. The New York-based paper cites in its review the ingredients in "Twilight in the Sierras" that made it yet another successful addition to the ongoing series of films by the King of the Cowboys. "Roy Rogers", reports "Motion Picture Daily", "gives his fans just about everything in this Trucolor western complete with perfect hero, dastardly villains, much suspense, a mountain lion and singing cowboys."
