Hellhole

Having witnessed her mother's brutal death, Susan (Judy Landers) gets amnesia from a fall while being pursued by the killer, Silk (Ray Sharkey). Awakening in Ashland Sanitarium, she is once again terrorized by Silk, disguised as an orderly. To pry an incriminating secret from Susan's brain, Silk forms an uneasy alliance with Dr. Fletcher (Mary Woronov), a psychotic scientist who has been testing a new lobotomy technique, using helpless inmates as her guinea pigs. These vicious experiments are carried out in the 'Hellhole,' a torture den awaiting Susan as its next victim.
