As the unsuspecting young women, Erika and Amy, get in their car, a sadistic predator in black equipped with a gas-mask knocks them out and abducts them. From this point on, an endless nightmare of unspeakable torment awaits the helpless victims--who are drugged and chained down by their throats to wooden tables--through a wide assortment of sharp instruments and common household tools. Always starting from left to right, the butchering begins, as a savage trio of desensitized executioners film the abominable act of sacrifice with their Super-8 camera. Is death the only means of salvation?

天主教会正试图拯救一个无辜的灵魂，使之免遭撒旦的蹂躏。一浪接一浪的圣人被派去对抗被附体

Trapped in the padded white room of an abandoned asylum, a helpless man awakens, only to find himself chained down to a medical chair. There, a demented surgeon and his equally deranged assistant embark on a seemingly endless series of chirurgical tortures, unlocking new levels of pain and suffering, one excruciating procedure after another. Intent on harvesting the captive's endorphin-infused blood, the maniacal doctor mutilates the feeble flesh and breaks the naked bones, until the phial is filled with the life-giving substance. However, in this hellish purgatory of anguish and torment, the man finds the strength to cling to hope, as he keeps finding hand-written notes in his grim cell. Could there be another tormented patient in this nightmarish facility? Is there an escape from the never-ending agony?
