A content-hungry video blogger named Sara, played by Desiree Akhavan, is desperate for truly unique material to revive her stagnating web series. When she responds to a cryptic online ad from a man claiming to be a serial killer who has lost his inspiration, she finds herself in the isolated home of Josef, portrayed by Mark Duplass. Far from being intimidated, Sara is professionally intrigued and sees this as the ultimate documentary subject, despite the obvious danger. Josef, a lonely and deeply disturbed individual, is equally fascinated by her lack of fear, creating a bizarre and unnerving dynamic between them. As the day unfolds, Sara pushes the boundaries of her own journalistic ethics, engaging in a psychological game with her host where the line between predator and prey becomes terrifyingly blurred. Directed by Patrick Brice, this found-footage horror-thriller masterfully sustains an atmosphere of cringe-inducing tension and dark humor, exploring the desperate need for connection and the unsettling nature of obsession.
