Neurotic Roslyn (Sara Foster) takes an unlikely night job, sorting files in a closed-down hospital. She is variously troubled by memories of a bad childhood, a cop (Michael Biehn) searching for a clawhammer-wielding serial killer, possibly ghostly apparitions, and seriously bad vibes in the fifth-floor psych facility.
She shares pizza and late-night chat with a smug psychiatrist (Cary Elwes), but her marriage to a taxi driver (Gabriel Mann) is rocky, and — this being a horror film — her mental composure deteriorates with every weird noise.
Though it has a creepy institutional setting, some okay acting and a couple of unnerving moments, Psych 9 suffers from ridiculous plot contrivances, a murky last act and a general sense of déjà vu.
