Divorced, unemployed, and pushing thirty after spending four years as a shut-in. Rinji has little to show for his life except his reputation as one of Japan's strongest online mahjong players. But when his ex-wife falls ill and their young daughter is left in his care, being good at a game isn't enough anymore. He needs to put food on the table.

So Rinji decides to do the one thing he knows how to do: play mahjong for money. But dominating online is one thing. Making a living in Tokyo's real-world mahjong parlors means facing hustlers, veterans, eccentrics, and killers at the table who have spent their lives paying for cash. Armed with his talent at online mahjong, Rinji sets out to prove that the one thing that made him a failure might also be the thing that finally makes him a father.
