In Old Colorado (1941) finds hard-working ranch owner Ma Woods about to lose her spread thanks to her foreman's underhanded doings, leaving it up to Hopalong Cassidy (William Boyd) and his pals to save the day.

It's fast-paced frontier action as Cassidy and California attempt to get the goods on a scheming rustler who's turned an abandoned mine into an underground cattle pen, in "Leather Burners" (1943). Features early appearances by Robert Mitchum and George Reeves. Next, what's worse than a gang of stagecoach robbers? How about a gang of singing stagecoach robbers? It's a musical "Stagecoach War" (1940), and only Hoppy can change these outlaws' tune. It's indeed a "Sinister Journey" (1948) for Cassidy when he has to go undercover to bring a band of murderous outlaws to justice. Also stars Clyde, Rand Brooks. And, after his father suffers a heart attack caused by a group of thieves, Cassidy enlists Lucky's help to catch the crooks, in "The Showdown" (1940). 5 1/4 hrs. total.
