In the near future, humanity has reached a disturbing equilibrium with technology, where most people have cybernetic implants that enhance their abilities. In this world, we meet an extraordinary woman named Major, who is a hybrid of human and cyborg. Rescued from a terrorist attack, she has undergone an experimental procedure that allows her to carry out security missions in a society where cybercrime has become a real threat.
As Major progresses in her role as the leader of an elite special operations team, she begins to investigate crimes related to a mysterious figure known as "The Puppet Master." This criminal can hack into people's minds, compelling them to commit atrocious acts under his control. Major's pursuit becomes a personal odyssey as she starts to question her own existence and the meaning of being human in a world where the line between the biological and the mechanical is increasingly blurred.
As she confronts this new threat and uncovers hidden truths about her own identity, Major must reconcile her quest for revenge with her search for humanity. An epic battle between the past and the present ensues, where the fate of her own life and that of society hangs by a thread.
