When a group of psychiatric hospital nurses invoke the spirit of Bloody Mary - a supposed urban myth - the slaughter begins. First, a young nursing assistant disappears, her body never found. Now, patients are turning up dead-battered beyond recognition, soaked in blood, their eyes ripped out. Mary's wrath has begun. Freed from her eternal prison behind the mirror's reflection, she unleashes a murderous, maniacal fury upon the asylum. Moving at will through mirrors, she strikes when her victims are unsuspecting, defenseless, and alone. Bloody Mary's legend is real, her vengeance is fatal, and to free her, all you have to do is say her name.
