We're All Going to the World's Fair

Casey, a lonely teenage girl living with her single father, records herself taking the viral "World's Fair Challenge". She documents the mental and physical changes that it causes her as she becomes increasingly enthralled by the role-playing horror game online. As reality and fantasy begin to blur, Casey reaches out to JLB, an equally lonely middle-aged man who claims to be monitoring her well-being, but soon realizes that she is trapped in a sinister online world where the boundaries between reality and simulation are irreparably broken.
