Bree stands up to Principal Perry's despotic rule of the school, so Perry makes Bree principal for a day to teach her a lesson. Under Bree's administration with Vice Principal Leo, the school becomes a happier place, much to Perry's dislike, so she enters the student body as a disruptive pupil. Meanwhile, Adam's super-strength hypes up and needs to be recalibrated. Struggling against Chase's efforts to dial it back to where it should be, Adam winds up shrunken to toy figurine size. Now that Adam's the shorter brother by far, Chase can't resist meting out some payback for years of short guy harassment.
