Johnny Mack Brown and Raymond Hatton once again play undercover U.S. marshals Nevada McKenzie and Sandy Hopkins. This time, Sandy's sergeant, Trevor (Jasper L. Palmer), is shot in the back by Slim Ramsey (Raphael Bennett), an outlaw he had been tracking. Masquerading as a desperado himself, Nevada manages to infiltrate Ramsey's gang and learn the identity of its leader, a villain named Farr (Edmund Cobb). Sandy, meanwhile, pretends to be an Indian trader and the undercover agents are helped in their investigation by Tober (Tom Quinn), a defecting gang member. The latter is being questioned by Paul (Riley Hill) and the murdered sergeant's pretty daughter, Mary (Jennifer Holt), when their cabin comes under attack from Farr and his henchmen. Happily, Nevada and Sandy arrive just in time to prevent a massacre.
