Tsunetaro Asakura AKA "Dynamite Tsune" is a talented gambler, but not infallable. After losing his Boss's money in a dice game he repays his debt by serving as a pit boss for a struggling coal mine in Kyuushu. Quickly there's trouble with the local mining competition, who doesn't always play a fair game. True to his hot-headed nickname, Tsune only gets into deeper trouble.
