While on a trip to Mexico, Lucas and Mark are accosted by a group of "banditos" who steal their horses, take Mark as a hostage and leave Lucas in the desert to die. Lucas frees himself and trails the group to a small Mexican village, where he finds the town too frightened of the banditos to fight them. With the help of a saloon dancer and her aged father, Lucas tackles the task of subduing the bandits single-handed.
