In 1968, Sanli Bang, on the coast of Yueqian, was dissatisfied with the monopoly of the organization and management rights of the eldest brother Yamamoto Tomizo (Akira Nishimura). The Fu'an group, Ruotou Kawada (Matsufang Hongshu), used force to force him to hand over the power of the yacht, horse racing and other industries. Although the deal was reached, Abe hated Kawada to the guts. Under the introduction of Uncle Wangu Kiichi (Miyazhao), Yoshimoto and Yoshiro Kanai (Mayichi Chiba) of Osaka Asano Group, want to get rid of Kawada with the help of foreign gangs. Wangu took this opportunity to become the leader of the Abe group, and then planned an ambush against Kawada. Kawada nearly died, and when he was not healed, he returned to Beilu to seek revenge and cut off one of Anben's arm. After he was released from prison, Kawada appeared to be obedient, but in fact he secretly colluded with the Asano group Okano group to plot a counterattack. A proxy war secretly manipulated by Osaka gangs soon began.
