Based on Stephen King's book, "The Girl Who Loved Tom Gordon" follows a young girl named Trisha McFarland who gets lost while hiking with her recently divorced mother and brother in the woods. Nine years old and scared of the dark, the girl winds up stumbling through the woods for nine days, wandering farther and farther from civilization even as she tries to make her way back home. As she walks, dehydration, hunger and exhaustion cause her to hallucinate, talking to several people, including her idol, a baseball player named Tom Gordon. But she also begins to believe that she's being stalked by a supernatural beast known as The God of the Lost, and soon her ordeal becomes a test of both her sanity and her ability to fight for her life.
