Six people wake up barefoot and amnesiac inside a pure white cube, remembering only the glamorous lives they once led. The hatch opens onto countless identical rooms stretching into infinity. This is an endless maze controlled by the super AI known as the Judge.
Every room has a numerical code. Make one wrong calculation, and a laser, scorching heat, or a blade trap awaits behind the door. The safe rooms, meanwhile, contain instruments of atonement tailored to a particular person.
The maintenance worker, Old Chen, is the first. A screen shows him taking bribes and falsifying an inspection report, causing someone’s death. The four walls close in, bristling with spikes. The moment he confesses, a mechanical arm descends: he must trade his hands for survival.
But the real rules are even crueler: the six must form a “circle of forgiveness.” Each person must be genuinely forgiven by another before the exit will open. Twelve hours later, the cube resets, and everything returns to zero.
One by one, the individual chambers arrive. The doctor’s indifference, the detective’s false testimony, the rich heir’s bullying, and the girl’s jealousy are stripped bare, layer by layer. But the architect Lin Yan’s sin is buried deepest: he once stood by and let someone die, driven only by the thought, “Don’t let them survive.”
The group betrays one another as the cycle repeats. A corrupt cop alters the coordinates, killing two people, only to be lured by Lin Yan into the central chamber. The three are linked by neck collars: if one lies, all three die. The moment everyone confesses, the exit opens.
Sunlight blazes outside the ruins. But pixel-like cracks begin to appear in the sky. The sunlight is simulated, and there’s a screen behind the clouds. The Judge’s voice falls from above: “You’ve passed only the first layer. True atonement is only just beginning.” An endless trial of self-deception and confrontation, harm and forgiveness.
