Flint spots a man collapse and offers him water. The man, Jupe, pulls a knife on Flint taking him captive. Jupe takes him to a camp where he sees Phelan who was kicked off the wagon train last year for stealing. The leader is Alexander Portlass who treats Flint in a civil manner compared to the others. He needs Flint's scouting skills to decipher clues on an Aztec tablet he stole that leads to Montezuma's treasure. He hopes to have a room at the British Musuem dedicated to his find. Flint escapes, recaptured and put in an Oregon boot to prevent another escape. He leads then to a canyon he believes might be the location. While collecting firewood, the Latigo Kid finds an Aztec war club. When he uses it in a fight with Jupe, Alexander is forced to kill Jupe to save the Kid. The Kid leads them to the site where he found the club which has writing on the wall. Flint finds a cave behind the wall. The Latigo Kid enters the hole resulting in his death as claimed by by the Aztec gods. Phelan traps Flint and Alexander who is sick and mentally unstable in the cave. Flint uses an Aztec bow and arrow to kill Phelan as Phalen shoots Bruto. The cave collapses on Alexander in his "room" freeing Flint.
