Shot on an iPhone – though you would never guess it – Steven Soderbergh's thriller is a reality-bending trip, and Foy is excellent.
Sawyer Valentini (Claire Foy) has been the victim of a stalker. Having moved to a new city, she still thinks she sees him everywhere. It's understandable, considering her trauma.
But when she attempts to receive help, her doctors have a different idea of what might be wrong.
