Plot

At an Idaho IGA store, a pregnant woman named Amber Lange runs into an old classmate and learns that Thayer Mangeres, a boy they went to school with, recently died after jumping into a river. Shaken, Amber reflects and flashes back to her days in high school as an unhappy but popular cheerleader and her interactions with Thayer, a “problem kid”. Because of their last names, they were often seated next to each other in class. In science class, Thayer drinks the blood of a dead fetal pig in an effort to impress his fellow students. Instead of being impressed, Amber is disgusted by Thayer, and tells him that she thinks nothing of him. Her casual dismissal sets Thayer on a course to make Amber's life miserable.
