Red River Range is a 1938 "Three Mesquiteers" Western film[1] starring John Wayne, Ray Corrigan, Max Terhune, and Polly Moran.

Wayne played the lead in eight of the fifty-one movies in the popular series.

The Cattlemen's Association has called in the Mesquiteers to find cattle rustlers.

This gets Stony into the gang of rustlers and he alerts Tucson and Lullaby as to the next raid.

But Hartley is on hand and unknown to anyone is the rustler's boss and he joins the posse with a plan that will do away with the Mesquiteers.
