Casey (a brilliant debut performance from Anna Cobb) is a lonely teen unhealthily obsessed with internet horror lore. Bored and looking for something to do, she takes the World’s Fair challenge - a creepypasta role playing game that supposedly leaves its players with inexplicable alterations. As she documents her experiences, she is suddenly reached out to by a distant stranger, veering Casey further into a dangerous, ever-blurring line between reality and mythology.

A haunting tale of loneliness and dysphoria that is at once both achingly empathetic and openly terrifying, this is a sinister and sad debut from Schoenbrun, who provides an exciting taste of where the future of the genre might lie.
