In a Japanese prison, a woman sentenced for a crime she did not commit faces the brutality of an unyielding prison system. Known as "the scorpion," she is a survivor who refuses to let her spirit be broken, despite the physical and psychological torture inflicted on her by the prison authorities and fellow inmates. As she tries to adapt to the violence and overcrowding of her surroundings, she quickly becomes the target of a group of inmates who see her as a threat.
However, instead of surrendering, our protagonist discovers an inner strength that drives her to fight for her freedom and that of the other prisoners. With cunning and determination, she begins to devise an escape plan that involves not only her own liberation but also the collaboration of other women who share her desire to break the chains of oppression. Along the way, she forges unexpected alliances and faces moral dilemmas that test her humanity in an environment that seems to strip her of all dignity.
As her story unfolds, deep themes emerge about the struggle against injustice, solidarity among women, and the search for redemption. This journey is not only a fight for physical freedom but also an emancipation of the soul in a place where hope barely seems to exist.
