Martial artist Takuma Tsurugi returns to take on a Yakuza family that may be embezzling money from charities to finance their own operations. Both the police and the Yakuza find themselves battling Tsurugi, but Tsurugi's fight ultimately is with the mob, and he concentrates on them.

Shozo Hirono has managed to separate from the Yamamori family and create his own small family, and extend his circle of acquaintances. These new friendships include a powerful underboss of the Muraoka family, Noboru Uchimoto.
