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.
