Former elite Special Forces commander Shi Hao loses his memory after saving his teammates and becomes a humble mountain hunter. Years later, his birth parents find him and force him to take the fall for their adopted son, Shi Chen, by marrying Su Qingyan—the "paralyzed" matriarch of the Su family. On their wedding day, Shi Hao whistles to summon mountain beasts, presents three legendary medicinal herbs as bridal gifts, defeats hostile bodyguards, and thoroughly humiliates Su Zhenhai, an ambitious uncle plotting a takeover. That night, Shi Hao discovers Qingyan's secret: she has feigned paralysis for three years to keep her enemies off guard.
When Su Zhenhai drugs Qingyan at a hotel, Shi Hao breaks in and rescues her. As Su Zhenhai escalates his scheme by demanding an ancient wilderness trial, Shi Hao leads Qingyan into the deep mountains, completing the trial with his animal allies and subduing armed mercenaries bare-handed. Triumphant, Qingyan rises from her wheelchair to officially claim her title. Panicking that Shi Hao will reclaim his birthright, Shi Chen colludes with Su Zhenhai to destroy the Su family's rare herbs before the prestigious Medicine King Banquet.
Though the villains kidnap Qingyan's ally Lin Wan to sabotage the event, Shi Hao storms their warehouse for a daring rescue, while Qingyan outsmarts them by secretly swapping in real herbs beforehand. At the banquet, Shi Hao enters with rare medicinal herbs, while flocking birds humiliate Su Zhenhai onstage. Exposed by secret recordings and mercenary testimony, Shi Chen and Su Zhenhai are arrested for their crimes. With Su Qingyan's leadership secured, the trio returns to Shi Hao's mountain village to build a thriving medicinal herb enterprise, embracing a bright, peaceful future together.
