The Seventh Dormitory is a dark allegory about the limits of human nature.
Eighteen amnesiacs awaken in a building trapped in an endless cycle, forced to take part in a survival game where one person is executed by vote each day. Black numbers appear on their wrists, marking each person's "sin score": pride, wrath, greed, lust... Once their sins pass a critical threshold, they mutate into nourishment for malice.
Architect Qin Yu awakens with fragmented memories of a past life and discovers that he is the key to the seventh cycle. He can foresee fragments of death, yet finds himself in an even deeper predicament: every attempt to save someone only accelerates their descent.
As the 21-day countdown ticks away, reason clashes with violence, and hope and despair spring from the same source. When the ultimate truth is revealed, that this is a prison created by malice to prove that "human nature is evil," Qin Yu must choose: become a perfect sinner, or become something that cannot be defined...
