John, portrayed by Scott Adkins, seemingly awakens from a nine-month coma, having been led to believe that a man named Deveraux brutally murdered his family. However, the shocking revelation is that this John is actually a new clone, crafted with fabricated memories of a family that never existed. The supposed crime never took place. An FBI agent, played by Rus Blackwell, approaches John immediately upon his awakening, bombarding him with questions and presenting a photo of the alleged killer, thus nudging John toward a path of vengeance against Deveraux.
The government has a vested interest in John, as Deveraux is known for operating an underground organization that liberates clones like John, restoring their autonomy and erasing their implanted false memories. As John ventures out into the world, he encounters familiar faces he has never seen before—an unsettling experience—hinting at a chaotic past laden with violence. For instance, his ex-girlfriend reveals he once assaulted a man mercilessly outside her workplace, sealing his fate as an unwelcome presence there.
Complications arise when John uncovers the horrific legacy of violence he has left behind, highlighted by a chilling encounter with a disfigured man in a storage unit, who demonstrates that John is responsible for a friend's death. Eventually, he discovers another version of himself—a previous clone who has been liberated by Deveraux and experienced a similar fate but without the false familial memories.
As the narrative unfolds, both John and Deveraux's factions are on a collision course, believing John to be a traitor. In a critical turn of events, after killing Magnus, his relentless pursuer, John confronts his original clone, culminating in an explosive revelation. When he is ultimately captured by Deveraux’s men, the layers of deceit are stripped away, offering him a stark choice: to erase his false memories, which initially he consents to, until the thought of losing the memories of his wife and daughter triggers a violent rebellion within him.
What began as a mission fueled by the government morphs into a personal vendetta, cleverly manipulating John's psyche to entrap Deveraux. Ignoring the complex web of truth and deception that surrounds him, John emerges as the leader of the universal soldiers following Deveraux's demise. The climax accelerates rapidly when John confronts the FBI agent once more, armed with the knowledge he has gained. In a dramatic conclusion, he retaliates against the agent, claiming his place and replacing him with a clone, thereby closing the circle of manipulation and retribution.
