The wicked brothers, Jim and Fred Mortimer, owners of the Overland railroad line, aim to bankrupt the rival company, Southern, in order to take it over cheaply: to carry out their plan, they resort to violence, hiring El Cuervo’s rebel Apaches and evil-doers of every kind! Railroad yards destroyed, workers’ pay robbed, bloodshed… Tex, supported by the stormy Irishman, Pat Mac Ryan, whom we find among the Southern workers, puts the brakes on the Native American raids and dismantles the saboteurs’ plots.
