Dan Stanton and Condon are foreclosing on a group of ranchers in order to gain a land-monopoly. They have one of the ranchers, whose property supplies the others with water, killed. Ann Jennings, niece of the rancher, sends for U. S. Marshals Nevada Jack McKenzie and Sandy Hopkins, who organize the ranchers who take over the dead man's property and blast the dam releasing needed water to all the ranchers. Nevada and Sandy, aided by the sheriff, round up Stanton, Condon and their gang members.

Range Law stars Johnny Mack Brown as "Nevada" and Raymond Hatton as "Sandy", the same characters they played in most of their mid-1940s Monogram westerns. This time, Nevada and Sandy, US marshals both, set out to collar some renegades who've been driving out the local ranchers. It's just possible that one of said ranchers is behind this land-grabbing scheme.

Taylor's men are robbing incoming supply wagons to enable Taylor to sell goods at inflated prices. The Vigilantes led by Frank Jackson are doing the same so the ranchers won't starve. Marshals Lash and Fuzzy arrive to try and find the real culprits.

A US marshal goes undercover to bust up a bunch of rustlers.

Set on the Mexican border in 1850, Bad Men of the Border was the first of seven Universal Westerns starring handsome Kirby Grant, a former singer from Montana who had earlier acted under the name Robert Stanton. The series, Universal's last attempt at competing with Republic Pictures' many streamlined B-Westerns, also featured the bucolic Fuzzy Knight as Grant's sidekick. Grant and Knight are undercover U.S. marshals tracking down a gang of counterfeiters. To their surprise, they are soon assisted by a beautiful Mexican dancehall performer, Dolores Mendoza (Armida), who proves to be an undercover agent as well, in her case for the Mexican rurales headed by Captain Garcia (Francis McDonald).

With the railroad coming, Nixon is after the ranchers land. Using a stooge land agent, his method is to claim the person they bought their ranches from never had title to the land and their deeds are worthless. Fereral Agent Johnny Mack arrives posing as a gunman. He is quickly onto the henchman and Land Agent and eventually suspects Nixon is the big boss. But he needs the help of ventriloquist Alibi to bring them in.

After a band of drunken thugs overruns a small Indian Nation town, killing Reverend Goodnight and raping the women folk, Eula Goodnight enlists the aid of US Marshal Cogburn to hunt them down and bring her father's killers to justice.

Bart Morgan controls the town of Cactus City and is keeping all men away from Jane Rankin. When Johnny Day arrives and takes an interest in Jane, Morgan tries to kick him out. Johnny refuses to go and the stage is set for a showdown.

Brown's principal antagonist this time is the town boss, an outlaw who has killed the community's leading citizen. The dead man's grown children want to investigate the killing, but the outlaw puts a stop to this by hiring a dance-hall dame to pose as the kids' long-lost mother. Johnny isn't fooled by this subterfuge nor is his sidekick.
