Mexico, 1915. US bank robber Tom Bryan hopes to retire to Mexico, where the ever popular ex-revolutionary dictator, Pancho Villa, has been deposed and driven to his home province by another tyrant. Colonel Castro's band of loyal Villa-supporters hope to get him back in power so rob a gold train. Aboard is Bryan, who was secretly paid to help. Delivering the gold to Pancho by Yaqui country proves harder, as the Indians help with the federales (government troops) in pursuit. More dangers lurk.
