***SPOILERS*** Unusual "One Step Beyond" episode in that besides telling a story about the supernatural it also has featured in its epilogue the person that the episode was based upon: Famed Mexican artist and world renowned philosopher Gerardo Murino Cornado know also as Dr. Atl. Dr.Atl escaping from prison back in 1920 after the president of Mexico, whom Dr. Atl was associated with, was overthrown by a military coup ends up in this Mexico City monastery on "The Night of the Ghost". That's when this 7 foot tall Aztec warrior comes back from the dead and seeks revenge for being murdered or sacrificed to the Aztec Gods back in the 15th Century.
As it turned out it was Dr. Atl's both good and bad luck to be at the monastery that evening in that he was later arrested not just from escaping from prison but for the murder of Captain Alverez, Robert Carricart, who was just about to shoot him and make it look like Dr. Atl resisted arrest! What in fact happened was that Capt. Alverez ended up being killed by the invisible Aztec ghost just as he was about to do Dr. Atl in! Arrested for Captain Alverez's murder Dr. Atl can only explain his death in ways that even he, a man of science ad logic, can't himself believe.
***SPOILERS*** Demanding that the person in charge of the military investigation Col. Rodolfo Acosta view Captain Alverez's body to see that he couldn't have possibly had murdered him Dr. Atl's is out of luck in finding out that his only witness monastery caretaker Carlos Gonzalez, Jay Novello, had suddenly died of a heart attack and that Capt. Alverez's body has since been cremated! It soon came out that a local artist Gomez, Rodolfo Hoyos Jr, had made a death mask of Captain Alverez for his graving wife just before he was cremated that may well prove Dr. Atl's claims that he wasn't the person who murdered him. Going to Gomez's Mexico City studio Col. Acosta is shocked to see that regardless of how incredible Dr. Atl's story was it in fact was true! The death mask of Capt. Alverez showed such major damage to his neck and face that it couldn't have possible been made by Dr. Atl or, with he exception of someone with the size and strength of "Andre the Giant", any other member of the human race!
