In a near future, where technology and biotechnology have advanced by leaps and bounds, humanity stands on the verge of a new era of power and control. Marisa, a brilliant young scientist but marginalized by her colleagues, develops an innovative program in neuroscience that promises to connect humans and artificial beings. However, her discovery attracts the attention of a powerful corporation with dark intentions that seeks to use her work to create bio-enhanced soldiers.
After a confrontation in her laboratory leaves her injured, Marisa is forced to flee and becomes a target for the company's mercenaries. What seemed like a moment of despair transforms into an opportunity, as by manipulating her own experiment, she becomes a beautiful yet dangerous hybrid being, a "vixen" with superhuman abilities and a brilliant mind.
As she tries to understand her new identity and the power she possesses, Marisa forms a resistance group with other outcasts who have also been victims of the corporation. The line between heroine and villain blurs as she fights to dismantle the system that seeks to strip the weak and uncover the secrets that brought her to this point. As tension rises and the final battle approaches, Marisa faces her greatest dilemma: can she save humanity without losing herself in the process?
