Contemporary Russia. A high school student becomes convinced that the world has been lost to evil, and begins to challenge the morals and beliefs of the adults around him.

After Venya's mother receives a call from school reporting her son's refusal to participate in mixed swimming lessons, she first suspects her teenager of being shy and derides his claim that it is "against his religion." As Venya is finally exempted by the school's devout principal, he grows confident that his strict and rigorous study of the Bible gives him the ability to manipulate all forms of authority. Challenged by a teacher who refuses to consent to his dogma, he sets out to eliminate her and subdue an entire community.
