Academy Award®-winning director Steven Soderbergh plunges audiences into the suspense and drama of a resilient woman's fight to reclaim her freedom even as she risks her own sanity. Still scarred from the trauma of being terrorized by a stalker, Sawyer Valentini (Claire Foy, The Crown) receives treatments at the Highland Creek Behavioral Center. However, shortly after she unwittingly commits herself to the mental institution and is unable to leave, she catches sight of a facility staffer who, she is convinced, is actually her stalker. But is he real or a production or delusion?
