Jimmy Morgan is possessed by an evil too powerful to be exorcised by any religion. After escaping from a mental institution, Jimmy returns with a vengeance -- and an army of children who follow his every murderous desire. The town trembles in fear as the youths attack and abduct its residents -- innocent and guilty alike -- dragging their victims to an abandoned castle and subjecting them to grisly torments deep within its underground tunnels. Those who discover the terrible secret behind the disappearances and deaths don't live long enough to tell it. The teacher, the doctor, even Jimmy's own brother and mother, will all confront their fates in the TORTURE CHAMBER.
