Unsane

“Is she or isn't she?”

Sawyer Valentini (Claire Foy) has moved to a new city to get away from a man who stalked her, and all she wants is an ordinary life. One visit to a counselor ends with her signature on a form and a locked bed in a mental institution, where staff insist she belongs. Steven Soderbergh shot it on an iPhone, and what he follows most closely is the tie between Sawyer and David Strine (Joshua Leonard), a face she knows from before.
