Pop Lawrence and his daughter Susan are barely making a living from the once prosperous mine they now believe to be picked clean. In reality, Big Ben Salter is secretly replacing high-grade ore with worthless rock just before each shipment is made. Marshal Lee Powell, working undercover, poses as an engineer to get the goods on Salter and risks his life in a daring game of cat and mouse.
Along the Sundown Trail is the last of six "Frontier Marshals" pictures made by PRC as starring vehicles for Lee Powell and country-western singers Bill Boyd and Art Davis. This film boasts a simple, straightforward plot that begins with the main conflict already underway and races toward its action-packed climax. Lee Powell, the screen's original Lone Ranger, makes a stoic lawman, and veteran Western heavy Charles King is in fine form as crooked miner Ben Salter. - Ed Hulse
