We're All Going to the World's Fair

“So you want to join the internet's scariest online horror game?”

The World's Fair Challenge is spreading online, and Casey (Anna Cobb), a teenager alone in her attic bedroom, signs up for the horror role-playing game. Jane Schoenbrun follows her as she films herself taking the challenge and posts the videos for anyone who wants to watch. Casey keeps recording through whatever it does to her body and her sense of what's real, with only a stranger named JLB (Michael J. Rogers) paying attention.
