A man in his thirties ventures from the city into the woods, where he pitches a tent to spend the night. As darkness falls, he hears a haunting howl and, upon investigating, is assaulted and knocked out. A mysterious 25-year-old man finds him and transports him to an isolated house, seemingly untouched by time. The Stranger regains consciousness in a bed, tended to by a 35-year-old woman who helps him recover. However, the Man and Woman engage the Stranger in a psychological game that tests his sanity to its limits.
