Valley of Hunted Men (1942)

"The Three Mesquiteers ride herd on range saboteurs!"

Fugitive Nazis threaten to take over the Wyoming range in this Three Mesqueteers outing, which also warns about the danger of blithely assuming that every German-American is a fifth columnist. Which is exactly what rancher Clem Parker (Hal Price) does when learning that a couple of escaped Axis war criminals may be heading towards the local valley.
