In a small town school, Mrs. Harper, the young and attractive schoolteacher, is known for her strict yet kind demeanor. One afternoon, during a physical education class, she leads the students in an intense game of tag. However, her strictness takes a surprising turn when she catches a student cutting corners and immediately spans his ass with a firm slap. Her authority is clear, but as she leans against her desk afterward, she feels a strange mix of power and tension that makes her think twice about her actions.
