Sonatine

Murakawa, a Tokyo yakuza tiring of gangster life, is sent by his boss to Okinawa along with a few of his henchmen to help end a gang war, supposedly to mediate between two warring clans. He finds that the dispute between the clans is insignificant and whilst wondering why he was sent to Okinawa at all, Murakawa’s headquarters are bombed and he and his gang are ambushed.
