Unsane trailer: This terrifying psychological thriller starring Claire Foy has been shot entirely on an iPhone

A young woman, who believes she is being stalked, does everything in her power to avoid the man following her. She changes phone numbers, email IDs, and addresses. She even gets a restraining order. But, one day, she’s held in a mental institution against her will. The hospital staff, who all appear to be cruel and evil, medicate her and tell her that she has agreed to be committed into a mental asylum. While in the institution, she again starts to get stalked by the same man, but is it all real or just her delusion?
