When the boy draws with the stick, his drunken father is attacked by a snake and vanishes. Years later, Alan and Becky are married to each other; while planting some flowers to celebrate the death of Alan's mother, Becky finds the box buried in the garden and she keeps the stick in her pocket. Meanwhile, five friends are traveling in a monster truck, drinking beer. The driver accidentally runs over Becky, but believes he had hit an animal.
