Hellhole

A young woman becomes amnesiac after an attack by a hired killer. She's admitted to a mental asylum run by a ruthless doctor who experiments on her patients with a lethal drug, and her attacker just got employed there.
An unlucky woman’s mother is murdered by a scarf-wielding killer named Silk, leaving the woman injured, traumatised 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, performing experiments in chemical lobotomies!
