Hopalong Cassidy rides into danger again with the hands of the Bar-20 Ranch in West Texas. Rustlers are running rampant and it is up to Hoppy and his sidekicks to find the man responsible. But be warned, this is NOT the Hoppy William Boyd protrayed on the Silver Screen and Television. Mulford's Hopalong Cassidy is a hard-drinking, roll-your-own smoking, itching to get rowdy cowboy ready to back the play of his friends at the drop of a hat.
