Yakuza gunman, Tachibana is released from prison after serving a 10-year sentence to find that his former gang is not nearly as respected as it once was. To make things worse, his wife has settled down with another man and his daughter Tomoko has all but forgotten him.
When Tachibana is sent a young hooker named Yuki as a reward for the hit that got him locked up in the first place, he ends up acting more like a father to her than a client. After forcefully helping her kick a nasty drug habit and beating up her yakuza-connected pimp, the two of them suddenly find themselves at extreme odds with their respective employers.
