Synopsis by Hal Erickson
This episode is based on an actual incident in the life of famed Mexican revolutionary and muralist Gerardo Murino Cornado, aka "Dr. Atl." On the run from the authorities, Atl (played by David J. Stewart) takes refuge in a convent that is allegedly haunted by the ghost of an aztec warrior. Of course, Atl is too intelligent a man to believe in such nonsense--until the Federale who is pursuing him is mysteriously strangled to death. The real Dr. Atl makes a guest appearance in the closing scene.
