Sara’s a video artist whose work primarily explores the intimacy of lonely men. One online advert intrigues her so much, she replies, thinking she may have found the subject for her next project. She drives to a secluded house in the forest, where a man claiming be the advert’s poster greets her; and as he said in the posting, he claims to be a serial killer (Mark Duplass). Unable to resist the chance to create a truly shocking piece of art, she agrees to spend the day with him. But, as the day progresses, she realises she might’ve put herself into a position from which she can’t escape.
