As their antics escalate, so does the personal risk, leading to a series of unexpected decisions that will change the fate of everyone in the ward. With a profound emotional backdrop, this story not only explores the struggle for identity and sanity but also delivers a biting critique of society and its institutions, showcasing how true courage can flourish even in the darkest of places.
