Behind its walls the treasure of kings. Getting in is easy. Getting out...Impossible!
Lost in the mountains and myths of Old Mexico, there is said to exist a fabled Aztec temple filled with gold. Drawn by the lure of untold riches, a mute named Flores leads a band of deadly commancheros in search of the treasure. A reckless young cowboy called the Pecos Kid is also on the trail but the Kid doesn't stand a chance against them. He has a friend who can make all the difference...a beautiful, platinum-haired, half-breed woman named Yellow Hair, a golden warrior who knows the mountain's dark secrets.
