Lu Qingyuan, the most famous psychological counselor in Jiangcheng, is famous for his calm and precise "scalpel" therapy. However, his perfect life was broken by a strange coincidence - many of his patients invariably described the same nightmare: a black figure with an unclear face, staring at them in an abandoned orphanage.
When Lu Qingyuan tried to use hypnosis to explore the source of the dream, he was horrified to find that the ruins and the black shadow perfectly overlapped with his dusty childhood memories. His forgotten past seemed to be screaming at him through the patient's nightmares.
In order to save the patient and to find himself, Lu Qingyuan embarked on a dangerous road to pursue the truth. Every step may lead to falling into the abyss of memory, and the "black shadow" lurking in the darkness is smiling, waiting for his return.
