Unsane

Sawyer Valentini (Claire Foy) relocates from Boston to Pennsylvania to escape from the man who's been stalking her for the last two years. While consulting with a therapist, Valentini unwittingly signs in for a voluntary 24-hour commitment to the Highland Creek Behavioral Center. Her stay at the facility soon gets extended when doctors and nurses begin to question her sanity. Sawyer now believes that one of the staffers is her stalker - and she'll do whatever it takes to stay alive and fight her way out. A young woman is involuntarily committed to a mental institution, where she is confronted by her greatest fear - but is it real or a product of her delusion? (20th Century Fox AU)
