Veteran burlesque comic Lee "Lasses" White replaced Emmett Lynn as comic sidekick "Whopper" in this fine Tim Holt Western for RKO. Whopper, Stan Bradford (Holt), and Smokey (Ray Whitley) are delivering a herd of pack horses to telegraph lineman Jeff Corbin (Dennis Moore) when intercepted by smooth-talking Cobb Wayne (Harry Worth), who is in a deadly competition with Corbin.
