The film opens with an assassination attempt on the Joseon king during a grand reception, a plot that is almost thwarted by a special security squad led by Gyu-yup. The event triggers a string of high‑profile political deaths, sending the kingdom into a tense nighttime skirmish where one member of an apparent assassin duo—a woman—falls into custody. Gyu-yup recognizes the captive, and as she refuses to reveal information, she endures brutal interrogation. This sequence sets up a sharp pivot: a flashback that takes us back to Gyu-yup’s past.
Shortly after the Japanese invasions of Korea in the middle Joseon period, a unit of elite soldiers is forged from students of the Clear Wind Shining Moon sword school, created to secure peace and protect the realm. At the center of this unit are two exemplary swordsmen, Ji-hwan [Choi Min-soo] and Gyu-yup [Bae Joong-sik], whose bond is unbreakable and whose skills define the training ground. Yet a political coup—often called a rebellion—threatens everything they have built. Gyu-yup is pressed into an impossible choice: he must kill his fencing master, and he must also confront Ji-hwan, who is entangled with Shi-yeong, the daughter of the fencing master and a skilled warrior in her own right. The burden is crushing, and the cost is mortal. In the midst of this upheaval, a harsh truth emerges: a line is crossed, and loyalty fractures.
During the upheaval, Gyu-yup is forced into brutal acts that devastate his inner world. He beheads his master, slays his best friend, and even confronts his best friend’s lover—an unnamed moral abyss that stains him forever. The rebellion also forces him to lead his troops against members of the very training school that shaped them, raising a chilling protest from within: “we have killed the brothers with whom we shed blood.” This brutal cascade crystallizes a lingering ache: a man who has lost a essential part of himself.
The narrative then returns to the present, five years after those fateful events. Gyu-yup has become a cold and dreaded commander, nicknamed “the human butcher.” A sword bearing the seal of his old unit surfaces during a night battle, suggesting that Ji-hwan may still be alive and active, not dead as Gyu-yup had believed. The current king—an usurper who navigates a treacherous landscape of betrayal and cover‑ups—begins to unravel, ordering assassinations of key commanders to hide his tracks. The king schemes to draw Ji-hwan and Shi-yeong out into the open, planning an expedition that could decide the fate of the rebellion once and for all.
As Ji-hwan and Shi-yeong become aware of the royal plot, they maneuver to avoid capture while contemplating a risky gambit. The expedition unfolds, and Ji-hwan nearly downs the king, only to be momentarily distracted by the death of Shi-yeong at the hands of the king’s elite guard. The moment is devastating, and it tests everyone involved. In a decisive turn, Gyu-yup, moved by past loyalties and the memory of Shi-yeong and Ji-hwan, steps into the fray to save his once‑friend. He pleads for a chance at freedom, a vow that had bound him during the rebellion years earlier, and when the king’s response remains silent, the two former allies confront the encircling troops side by side. What follows is a breathless, cataclysmic clash in which old bonds are revived only to be tested once more.
The film concludes with a powerful freeze-frame: the two men—once rivals, now united in their resistance—fight shoulder to shoulder against the usurper king’s troops. The reunion is tinged with sorrow and clarity, a testament to the brutal cost of loyalty, duty, and friendship. Through its sweeping flashbacks and intense present-day confrontations, the story remains focused on the core relationships that define the saga—the bond between Ji-hwan and Gyu-yup, the memory of Shi-yeong, and the unyielding pressure of a kingdom unwilling to forgive betrayal.
The tale is a grim meditation on sacrifice and memory, where past loyalties collide with the demands of the present, and where two once‑brotherly swordsmen must choose between the promises they’ve made and the lives they’re willing to fight for now. The balance between honour and survival threads through every battle, every interrogation, and every quiet moment of reflection that follows a victory hard won and a friendship tested beyond endurance.
