Plot

Dr. Sun spearheads a resistance to liberate China from Japanese rule, facing relentless attacks from assassins sent by the Manchu authorities during his travels. The Chun Do martial arts school is assigned to protect him throughout his journey. Simultaneously, Chen Zhen encounters a Russian combatant who, rather than seeking to eliminate him, is eager to master the intricacies of Chinese kung fu. As tensions rise, the clash of cultures and fighting styles intensifies, setting the stage for a battle of wits and strength.
