Dead or Alive (DOA)

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.

Two contract killers cross paths in the middle of the same job and realize they are childhood friends. Together they take a break from killing and visit the small island they once called home. After reflecting on their past lives they decided to team up and use their talents in killing for good... much to the upset of the crime syndicates.

Set in a post apocalyptic Yokohama where the population is kept under rigid control by a half crazed mayor, Riki Takeuchi is a hard boiled cop and Show Aikawa a mellowed out drifter that hooks up with a gang of rebels. When the gang kidnap Takeuchi's son, the wheels are set in motion that leads to an inevitable showdown.
