The narrative follows a soldier from a defeated nation who has been captured and imprisoned. Under the guise of "re-education" and compassion, the protagonist is subjected to a systematic process of breaking his will. Set within a dungeon environment designed to strip away adult rationality, the prisoner is manipulated into a state of infantile regression. The captor, an invading woman who demands to be called "Mama," uses psychological conditioning and humiliation to crush the protagonist's dignity. The "training" focuses on total dehumanization: the protagonist is forced to abandon his intellect and his loyalty to his homeland. Ultimately, he is reduced to a mindless subject whose only purpose is to serve as a source of "sustenance" for his captor, completely losing his identity and autonomy in the process.
