Lin Mu, a young and promising psychiatrist, was forced to return to "Blackwood Manor" where his family has lived for generations after receiving a mysterious letter from his estranged grandmother. The letter contains vague references to family curses, dusty truths, and a unique "legacy." Lin Mu, a staunch believer in science, initially scoffed at this, thinking it was just the gibberish of an old woman. However, driven by an indescribable sense of responsibility and curiosity about the mysterious history of his family, he embarked on his return journey.
Lin Mu tried to use science and reason to interpret everything, but was troubled by a series of unexplained strange things, the twisted minds of family members, and ancient legends. He gradually discovered that the "curse" was not a illusory superstition, but the embodiment of psychological trauma and sin passed down from generation to generation in the family. In the process of searching for the truth, he not only has to fight against the shadows entrenched deep in the manor, but also faces his inner fear and resistance to his family's bloodline. In the end, can he uncover the secrets of Blackwood Manor, break the shackles passed down from generation to generation, and find his own salvation, or will he be completely swallowed by this endless fog?
