Suzuki is the last remaining member of the school swim team. If no new members join the team this year, they will be forced to withdraw from competing. Fortunately, a pretty girl named Sakuma is selected as the swim team's new coach. In a funny twist, she decides to train the team in synchronised swimming, scaring off most of the male students. All but five persistent young men decide to remain, in the hopes of trying to save their swim team.
