In this his penultimate Western for low-budget company Monogram, Jack Randall assumed the identity of a murdered ranger in order to track down the killer. In the lawless town of Brimstone, the citizens are being terrorized by a gang of outlaws headed by Mason (Tom London), who, to no one's great surprise, proves to be the very man Jack has been trailing. The relieved citizens of Brimstone then elect Jack as their new sheriff. The murdered ranger's sister was played by Margaret Roach, the 19-year-old daughter of comedy producer Hal Roach. Ernie Adams replaced Glenn Strange (who himself had replaced Frank Yaconelli) as Randall's sidekick, Manny, and Nelson McDowell provided additional comic relief as Brimstone's busy undertaker.
Unfortunately the movie Riders from Nowhere is not yet available on Disney Plus.
