"Ah! That Pep Squad" is based on a comic book sensation that swept the nation. As director Chusei Sone's adaptation of the story delivers the guffaws and excitement of the original comic, first time actor Hitoshi Imai nails the lead role of Akamichi Aota. Aota is a strong-armed barbaric women chaser that acts out of sheer instinct. As commander of the South Kawachi College Pep Squad, he leads a group of do-or-die freshmen and bossy seniors into a whimsical tale of lust, discipline and violence.
Life in the pep squad is all about harsh discipline. Seniors are "Gods", juniors are "Humans", sophomores are "Slaves" and freshmen are treated like "Trash". One sunny day, two freshmen are entrusted with the task to dry out the squadron's flag; the most cherished and symbolic item of the squad. When they accidentally burn a hole in the flag with a cigarette, they blame Aota. Aota attempts to take full responsibility by committing "harakiri", but changes his mind during the process – a deep stab to the stomach has inspired him with a better idea.
