Jiang Che and Xia Wan were involved in a nightmare game that started on time at midnight. As a game designer who suffers from frequent insomnia, Jiang Che can always enter strange game instances in his dreams, and Xia Wan, a forensic doctor with the ability to predict dreams, can decipher the death omens in the instances.
The heartbeat of an abandoned hospital, the distress letter in the wardrobe of an ancient house, and the death song played repeatedly on campus. Each copy corresponds to a bizarre murder case in reality. Jiang Che's gaming talent can find loopholes in copies, and Xia Wan's scalpel can cut off the obsession of resentful spirits. The two have gone from being suspicious of each other to teaming up to break through levels, fighting against the evil spirits hidden behind nightmares in the intertwining of dreams and reality.
When the game clearance progress reaches 99%, they find that they have become the prey of the nightmare master, and the ultimate reward of the game is to rewrite the contract of life and death...
