The World, the Flesh and the Devil

African-American coal mine inspector Ralph Burton (Harry Belafonte) becomes trapped underground in a cave-in while inspecting a mine in Pennsylvania. He can hear rescuers digging towards him, but after a few days they slow down and then stop completely. Alarmed, he digs his own way out. Reaching the surface, he finds a deserted world. (No bodies are seen at any time in the film.) Some discarded newspapers provide an explanation: one proclaims "UN Retaliates For Use Of Atomic Poison", another that "Millions Flee From Cities! End Of The World". Ralph later plays tapes at a radio station that an unknown nation had used radioactive isotopes as a weapon, yielding a dust cloud that spread globally and was completely lethal for a five-day period.
