George and Harold have discovered the perfect setup. They and their time-traveling doubles, Yesterday George and Yesterday Harold, take turns attending school and hiding out in their tree house playing video games. The arrangement works beautifully until they notice something disturbing happening to their classmates. Their cruel gym teacher, Mr. Meaner, has developed a sinister mind control technique that turns normal kids into eerily perfect, obedient students. The smell alone should have been their first warning that something terrible was brewing in Ohio. Now George, Harold, and their yesterday selves must work together to stop Mr. Meaner before his control spreads beyond their school. The fate of free-thinking children everywhere depends on whether four mischievous boys can outsmart an adult bent on creating a world of mindless conformity.
