Dr. Tarr’s Torture Dungeon, also known as Mansion Of Madness. A mysterious man is sent into the forest to investigate the bizarre behaviour of the notorious Dr. Tarr. What he stumbles upon is the doctor's torture dungeon, a hellish asylum completely cut off from civilization and presided over by the ultimate madman. Innocent people have been savagely chained, tortured and stuck in glass cages, then forced to take part in gruesome games of ritual slaughter.
