 Treasury agent Steve Ransom (Charles Starrett) is given the mission of unmasking Jonathan Cole (Fred Sears), head of a gang of smugglers operating near the Mexico/Texas border which is not within the length of three eastern seaboard states of Amarillo but Columbia title writers were never good at geography. In spite of Steve s warnings, his bumbling pal Smiley (Smiley Burnette) does some lone-wolf sleuthing on the Cole ranch and is taken prisoner just as Steve is getting the evidence he needs against Cole.
