When Elle, battling depression, becomes convinced that Katie is actually a flesh-and-blood human being, it sets her on a reckless and terrifying course. An exploration of the potentially dangerous allure of the Internet, the film picks up where its predecessor, the cult hit Ask Me Anything, left off.
