A series of strange and mysterious events unfolds around Guan Lin, who is writing a scholarly work on Dream of the Red Chamber. His family genealogy vanishes without explanation, someone alters and sabotages his research, and the strange behavior of his neighbors Ma Tianlong, Bai Xiaowen, Xiao Yating, and Wang Jingrui leaves him baffled. His lover Fang Ying's actions plunge him into even greater confusion.
As Guan Lin and his girlfriend Fang Ying investigate the secrets of Dream of the Red Chamber, whenever Ma Tianlong appears, mysterious assassins come after him.

The extraordinary martial arts skills of Kang Yufeng and Fang Ying raise Guan Lin's suspicions.

After enduring countless hardships and dangers, Guan Lin and Fang Ying finally crack the secrets of Dream of the Red Chamber. As the mystery gradually unravels, a startling historical case emerges. The story of Dream of the Red Chamber conceals a tragic historical truth. Could everyone around Guan Lin really be ghosts from more than two hundred years ago?
