Keiichi is a young man unable to swim due to fear of the water. Everything changes for Keiichi when he is dragged to a fitness club and quickly becomes enamored with one of the swimming instructors, Shizuku. He becomes determined to learn to conquer his fear in order to win her heart.

Nothing runs smoothly for Keiichi as he always becomes terrified whenever he comes in contact with water. To make things even more difficult, Keiichi finds himself swept away by the beauties that frequent the club and are eager to seduce him.
