A yakuza of Chinese descent and a Japanese cop each wage their own war against the Japanese mafia. But they are destined to meet. Their encounter will change the world.

Without a home and feeling no obligation to Japanese society or Yakuza, Ryuichi (Takeuchi Riki) and his small group decide to make their own place by trying to take over the Shinjuku underworld and the drug trade from Taiwan. As they plan an all-out-assault on the remaining Chinese and Japanese mafia kings, only Detective Jojima (Aikawa Sho) stands between them and complete domination.—anonymous

In Japan, after a massacre of Japanese and Chinese gangsters, the tough and persistent Detective Jojima is in charge of the investigations, while dealing with a personal family problem. His daughter needs to be submitted to a surgery and he needs to raise twenty millions yens urgently. He finds that the Chinese descendant Ryuichi has associated to a Taiwanese drug dealer and is eliminating the competition. In the end, their confrontation becomes a personal issue for both.—Claudio Carvalho, Rio de Janeiro, Brazil
