Gunmen of Abilene top-bills Republic western hero Allan "Rocky" Lane and his horse Black Jack. Lane plays a U.S. marshal who is sent to investigate a reign of outlaw terror in Abilene. He arrives in town incognito, securing a job as deputy sheriff. Soon he discovers that the outlaws want to scare off the populace so that they can claim the gold ore that rests beneath the town. It's no surprise that Roy Barcroft is the chief heavy, though it is a bit startling that Barcroft's partner-in-crime is played by Peter Brocco, an actor usually cast as a pasty-faced gangster henchman or communist spy. ~ Hal Erickson, Rovi
