Hellhole (1985)

aka: Hell Hole

An unlucky woman’s mother is murdered by a scarf-wielding killer named Silk (Ray Sharkey), leaving the woman (Judy Landers) injured, traumatized and suffering from amnesia. She’s committed to a mental institution, where Silk follows her, looking for the papers he was trying to get from her mother. And Silk’s only the beginning of her problems, since the asylum is run by a mad doctor (Mary Woronov) performing experiments in chemical lobotomies! Also with Marjoe Gortner, Edy Williams, Terry Moore and Dyanne Thorne.
