When the mobster Iwaida Nishikawi is executed by the hit man Takeshi, his family chases the killer. Takeshi's brothers Takashi and Hideshi Miwa try to find Takeshi, who is hidden with the nurse Rie Ishibashi, to protect him and Hideshi discovers that Takeshi was secretly sent by their Yakuza boss to eliminate Iwaida. Meanwhile, the mobster Kenmoshi abducts Takashi's wife Mariko and rapes her, trying to force Takashi to deliver his brother to him.

Inugami Sahei (Nakadai Tatsuya), who built up the wealth of the Inugami Clan, passes away, leaving a will with Furudate, his legal adviser, for his daughters Matsuko (Fuji Sumiko), Takeko (Matsuzaka Keiko) and Umeko (Manda Hisako), all of whom have different mothers, and for their sons (Sahei's grandsons), as well as for Nonomiya Tamayo (Matsushima Nanako), the granddaughter of a person to whom Sahei feels heavily indebted. The will states that all his assets are inherited by Tamayo alone, on the condition that she marries one of the sons of the daughters. Furudate's assistant learns the content of the will, and seeks advice from Kindaichi Kosuke (Ishizaka Koji), a private detective, as he senses the air of unease. Shortly afterwards, murders start to occur one after another in the clan.
