"Faith will always prevail," is Doctor Bible's motto and the winning card for Professor Banetti, an unbeliever, to solve the diabolical mystery in Stonehenge. For centuries, Satan's archenemy has been held captive by Satan in the mystical circles of Stonehenge. Known by many names and disguised in many forms, the time of freedom for Satan's enemy has come and if he wins in the ultimate cosmic battle he will be Lord not only of Hell but of all Earth. There are only two people who can unfold his plan, Otello Banetti, a professor and scientist obsessed by the occult, and his friend Doctor Bible, an expert in the scriptures. Devastating earthquakes and tsunamis are the only signs of the clashes between the two evil forces until Satan's enemy arrives in front of mankind disguised as the new Messiah ready to lead us straight to Hell.
