Rustler's Valley finds Hopalong Cassidy trying to help his young friend Lucky Jenkins out of a real jackpot. The young man has been accused of a bank robbery and evidence planted at the bank against him.
The villains are the usual, a banker, a crooked ranch foreman, and a shyster lawyer all conspiring to get a hold of Morris Ankrum's ranch. The lawyer has his own plans, he's going to marry Ankrum's daughter Muriel Evens.
Ankrum this early in his career is billed as Stephen Morris. But our lawyer is played by none other than Lee J. Cobb, billed here with the traditional western sounding name of Lee Colt. Under any name Cobb is a nasty and crafty villain who has a real mean on for Hoppy.
There's a real nice shootout between the outlaws and Ankrum's men. And Russell Hayden and Gabby Hayes find a really unique way to bring a sudden halt to the shootout.
Hoppy's fans should be pleased like I was.
