唯野高校水泳部の名をいっきに高めた学園祭のシンクロ公演だったが、学業を優先させるために水泳部に対して公演自粛が言い渡された。シンクロチームのリーダー・進藤勘九郎は、水泳部とは別にシンクロ同好会を設立、水泳部の顧問だった佐久間恵を新たな顧問としてメンバーを集め始める。果たして学園祭までに５人そろえてまともな演技が出来るのか…。大ヒット映画「ウォーターボーイズ」の２年後を舞台に、男子高校生たちが再びシンクロに挑む青春コメディ。
Two years ago, five high-school boys brought fame to a small town in Japan. What was so unique was that they formed a "men's synchronized swimming club." Their involvement and struggles while learning synchronized swimming - known to be a sport for girls - brought much attention to their school and town. Two years have passed since that summer, and the boys of Tadano High School are still in the club. The Fuji Television drama "Water Boys" shows how these young boys fight to learn synchronized swimming, fall in love, and enjoy friendship with one another.
