While mahjong is a game that is frequently played with family and friends, it is also a game that is played in some of society's most secluded areas. Nangou is a compulsive gambler who owes over three million yen in debt. He gambles his life on a game of mahjong with the mafia in a last-ditch effort to clear his record. Unfortunately, as the game proceeds, Nangou gets closer to death and further away from the prize.
