Six scientists arrive at the creepy Headstone Manor to investigate a strange phenomena which was the site of a mysterious massacre years earlier where 18 guests were killed in one night. It turns out that the house is the place of a satanic cult lead by a minister monk who plans to kill the scientists who are inhabiting this house of Satan.

Wealthy businessman Ross Webster discovers the hidden talents of Gus Gorman, a mischievous computer genius. Ross decides to abuse his talents, in a way to help Webster with his plans for economic control. When the man of steel interferes, something must be done about Supes. When Gus' synthetic Kryptonite fails to kill Superman, it turns him in an evil incarnation of his former self. The tar-laced Kryptonite pits man against himself, setting up the Clark vs. Superman battle.

From the dawn of man to the distant future, mankind's evolution (or lack thereof) is traced. Often ridiculous but never serious, we learn the truth behind the Roman Emperor, we learn what REALLY happened at the Last Supper, the circumstances that surrounded the French Revolution, how to test eunuchs, and what kind of shoes the Spanish Inquisitor wore.
