Filipa is an average 16-year-old girl leading an ordinary life until a catastrophic night changes everything. Witnessing the destruction of her beloved city and the cold-blooded murder of her parents by black-masked men, Filipa flees for her life. However, her escape is short-lived as she is apprehended and finds herself incarcerated in a prison run by masked men with chess symbols on their arms. Every day, scores of inmates vanish or perish, and more prisoners arrive. As Filipa learns more about the prison, she realizes that each chess symbol denotes a masked man's position and role. She is subjected to gruelling physical and psychological examinations, administered mysterious serums, and witnesses strange phenomena. Her mission is to uncover the masked men's identities, their motives, and above all, rescue her friends and save her love interest.
