True Legend movie presents a tiff between two brothers namely, Su Qi-Er and Yuan Lie. Su Qi-Er is apparently the king of Qing dynasty, who decides to adjourn his rule, since he harbors the dream to master martial arts, and to have a peaceful life with his family.
But he is unaware of a foe within his empire, who doesn’t want him to lead a happy and peaceful life. That man is none other than his own adopted brother, Yuan Lie, who extorts Su’s son and drags Su to kill him. However, he doesn’t succeed in killing Su, as Su’s wife comes to his rescue. Also, a cloistered doctor named Yu assists in healing Su. The speed with which Su recovers from his ill-health is much less than the speed with which his mind is contemplating to overpower his brother by mastering martial arts.
Once he recovers from his injuries, he seeks help from God of Wushu and Old Sage to depose his foster brother and earn his son back. He learns the skill of Drunken Boxing and sets on a mission to oust his brother from the region of Qing.
