Did you ever wish with all your heart to achieve some apparently unattainable goal? A group of high school graduates, led by Moss (Prangthong Chsngthom), do just that, embarking on a terrible journey into the unknown. Pushed by peer and parental pressure, they visit a mysterious shrine, offering gifts to a vengeful ghost, Kaew (Thitima Maliwan), and pledge their souls, rather than fail their entrance exams into prestigious universities. Their desires are met, but at a grim price. No one, least of all the skeptical Moss, believes that a mere slip of the tongue will lead to the death of her friends. The hateful spirit has some wishes of her own, and her demonic demands lead to a trail of doom and despair.
