A legend opens with Bodhi, an Indian Buddhist monk who discovers the art of Kung Fu and believes that his mummified remains hold mystical powers, a tale that threads through the ambitions of a ruthless gang and the fate of those who cross their path. The Dark Stone gang learns that half of the remains lie with Prime Minister Zhang, and they dispatch assassins to kill him and his son Renfeng. The gang’s top assassin, Drizzle, escapes with the coveted relics after a tense pursuit atop a bridge, leaving a trail of questions and danger in their wake.
On the run and haunted by the act, Drizzle encounters Wise Wisdom, the monk who will test her abilities and her conscience. Wisdom, a master of the blade, reveals to her that her swordsmanship has four fatal flaws and warns that she could be killed by a true master. In a tense three-month alliance, Wisdom tries to nudge her toward a different life, but his effort ends tragically with his death at her hands—an arduous demonstration meant to enlighten her, and a burden that weighs heavily on her.
Grief and guilt steer Drizzle toward a surgeon who reshapes her appearance, allowing her to assume the identity of Zeng Jing, a modest cloth merchant. As she rebuilds a life, she catches the eye of the messenger Ah-Sheng, a man she will come to marry, a bond that soon becomes entangled with the darkness she fled. Back with the gang, Wheel King—Dark Stone’s calculating leader—recruits and trains a fresh killer, Turquoise, a merciless girl who murdered her fiancé and in-laws on her wedding night. The pursuit intensifies as the gang presses on the trail of Drizzle and the missing remains.
The chase leads to a bank in a bustling market, where Drizzle—now living under the name Zeng Jing—manages to thwart a robbery with remarkable skill, saving both herself and her husband. The act, witnessed by many, exposes her whereabouts to the Dark Stone gang. In response, Wheel King summons three assassins—Leì Bin, the Magician, and Turquoise—to hunt her down. Although Turquoise has already shown herself to be dangerous, their mission remains singular: capture Drizzle and secure the remains. The trio closes in, and the tension mounts as Drizzle, still yearning for a quiet life, finds that freedom may come at a price.
The Wheel King’s demand becomes clear: in exchange for safety for themselves and a measure of liberty, they must surrender half of the remains and assist in collecting the other half. Drizzle agrees to hand over her portion, but the gang refuses to release her, and infighting among them leads to the Magician’s demise. Wounded, Drizzle staggers home to Ah-Sheng, who stands by her side even as danger closes in from every quarter. The killers press on, but Ah-Sheng, with a surprising turn of skill, reveals Cen-Ci swords—weapons that prove to be Renfeng’s—and halts their pursuit one by one. The revelation hits hard: the messenger Ah-Sheng is in fact Renfeng, whose life was saved by a ruse that left him for dead because of his situs inversus, and who has reshaped his appearance to avenge his family.
The truth devastates Drizzle as she grapples with Renfeng’s love and his vow for revenge. He confesses that love is impossible given the harm she and the Dark Stone gang have caused, yet he cannot bring himself to kill her and urges her to leave. The Wheel King continues his pursuit, leveraging his own frailties and power to trap his enemies. Turquoise learns a cruel truth about his plan and expresses her disgust, only to be buried alive beneath a bridge after her reveal of the Wheel King’s schemes.
As Drizzle decides to confront the Wheel King in a final showdown, she signals Renfeng with a crackling glow of fireworks from afar. Renfeng’s body, however, appears lifeless, a ruse that allows him to witness Drizzle’s last stand and the culmination of their vengeance. Drizzle engages the Wheel King in a brutal and decisive battle, drawing on Wisdom’s teachings to land a fatal strike. The Wheel King is wounded fatally, and Renfeng awakens, overcome with relief as he realizes that his family’s quest for justice has found its end, if only momentarily.
In a poignant twist, Renfeng discovers Drizzle alive rather than dead and carries her in his arms, his heart buoyed by the possibility of a shared future. Drizzle whispers a surprising line that underscores her intent to move forward together: “After we get home, draw up the divorce papers.” Renfeng laughs through tears, acknowledging the long life they have ahead, and the couple faces a future that promises healing and endurance after the storm of vengeance.
