Michael and Julia travel to the remote Two Rivers Ranch to spend a romantic weekend alone in a lodge, nestled deep in the Rocky Mountains. As the weekend begins the couple meets the caretaker, Henry, who seems suspiciously unfamiliar with the surrounding area. Little by little, they develop more questions about their weekend retreat that raise suspicion about the fate of the previous guests. As their suspicions continue to grow they discover the biggest secret of all; Desi, a thirteen-year-old girl alone in the dark hallways of the lodge.

Before too long their idyllic getaway becomes a life and death struggle that pits Michael and Julia against the only man for miles and more importantly, the lodge itself.
