Because Huo Yuanjia accidentally injured someone three years ago, following his father Huo Endi's command he sealed his fists for three years, enduring hard days working as a laborer at the Tianjin docks. When his son Huo Dongge conflicted with others to defend him, his wife and son were kidnapped by Zhang Biao of the Green Gang. Huo Yuanjia displayed his Mizongquan ultimate skill to rescue his wife and son, but was set up by Zhang Biao in alliance with Sakura Country's Sato. To rescue his father-in-law Wang Wu and clear his name of grievances, Huo Yuanjia shouldered the plaque of martial spirit and single-handedly stormed Hongbin Building, defeating eight sect masters and exposing the conspiracy of Sato and Zhang Biao colluding and trafficking opium. In the end, Huo Yuanjia defeated Sato, comprehending the true meaning of 'stopping conflict is martial', and resolved to carry forward the Huo family fists, guarding the Tianjin martial arts world and national righteousness.
