Face of the Screaming Werewolf

Experimenting in hypnotic regression to past lives, Dr. Edmund Redding of the Cowan Institute in Pasadena has discovered that Ann Taylor is a reincarnated Aztec woman. Via her recovered memories, she is able to lead Redding and his associates to a hidden chamber in the Great Pyramid of Yucatan, where they hope to find the lost treasure of the Aztecs. Instead, they find two mummified bodies - one of a modern man, quite dead, and the other of an ancient Aztec, quite alive.
