Chamaco finds himself on the wrong end of a firing squad after tracking an ex-Confederate to interrogate him about General Beauregard's missing gold. He's saved by a stranger who calls himself Stuart Byrnes. Stuart claims to know the location of Beauregard's strongbox, and so Chamaco takes him to Blake's camp. After a sort of initiation by the gang, Stuart leads Blake's men back across the border to Durango to retrieve the gold.

A young boy witnesses his parents' murder. Later, as he grows up, he befriends a bear in the wilderness and the chief of a local Indian tribe, and he stays with the Indians, but makes an enemy of the chief's son. As he enters adulthood he sets out to find the men responsible for his parents' deaths.
