The 5 billion yen drug operation ended in failure due to a trap set by the Tomoe family. As Riasaki (Hitoshi Ozawa) and Hidari (Hideo Nakano) investigate the truth behind the situation, they finally encounter a man named Igarashi, who has just returned from China. While Riasaki weakens under the pressure from within the police and threats from the Chinese mafia, the blood purge from Sakaki (Sho Aikawa), the third chairman of the Kanto Black Iron Alliance, is carried out.
