Shohei Sugiyama (Koji Yakusho) seems to have it all -- a high-paying job as an accountant, a beautiful home, a caring wife and a doting daughter he loves dearly.

However, he feels something is missing in his life. One day while commuting on the train he spots a beautiful woman staring wistfully out a window and eventually decides to find her. His search leads him head-first into the world of competitive ballroom dancing.
