A renegade doctor is shot dead and entombed with his fiendish experiments in the basement of an abandoned wing of a mental hospital. Twenty years later, a mysterious woman is admitted with amnesia, and her arrival is marked by an earthquake - which cracks the seal to the Dead Pit, freeing the evil doctor to continue his work.

After witnessing her family be murdered by the Russian mafia as a young girl, a woman vows to seek revenge on them when she has the chance.
