美国豚鼠2:血腥冲击 (2015)

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?
