Plot Progression

1. Evidence Against Ran — A nighttime hit-and-run leads investigators to Ran through surveillance footage and her overheated car. Ran denies driving, while Jin suddenly claims responsibility and invokes a prior dream.
2. The Medical Explanation — The Doctor proposes severe sleepwalking as an explanation for Ran's apparent actions and recommends settling the accident. Jin then reveals that his vivid dreams have continued for about a week.
3. Entangled Dreamers — Jin's dreams lead toward the former lover he misses, while Ran sleepwalks toward the man she despises. They realize that their dreams and movements are connected and attempt to control them together.
4. Murder Without Certainty — Exhaustion defeats their precautions, and jealousy turns their cooperation into mutual accusation. A dream appears to involve murder, but the characters cannot establish whether the crime is real.
5. The Unresolved Boundary — Ran is found holding the weapon while Jin confesses and defends her innocence. Their removal and the final accusation preserve the uncertainty between dream and reality.
