Ryuzo (Tatsuya Fuji) is a retired yakuza gangster who lives a quiet unassuming life with his salaryman son, Ryuhei (Masanobu Katsumura). Still in contact with his former lieutenant, Masa (Masaomi Kondō), Ryuzo maintains his short temper with their regular get-togethers. One day, the old gangster receives a call from an impostor pretending to be his son asking for ¥5 million. Ryūzō sees through the trick and learns from police detective Murakami (Beat Takeshi) that a member from the Keihin Rengo gang is responsible. Re-uniting his seven former henchmen to strike back, Ryūzō learns that they have all grown weak with their old age. The elderly yakuza members soon learn that they must overcome their weaknesses if they are to prove to be a match against the younger Keihin Rengo.
