Leigh Ann Watson (Katie Holmes) is the brightest girl at Grandsboro High...but her dreams of a much-needed college scholarship are sabotaged when her history teacher, the dreaded Mrs. Tingle (Helen Mirren, Red), falsely accuses her of cheating. Desperate to prove her innocence, Leigh Ann conspires with her friends Luke (Barry Watson) and Jo Lynn on a scheme that will teach Mrs. Tingle a lesson of her own. Before they know it, however, their plan spins hilariously out of control.
