In the first year of the Tang Dynasty, Empress Wu held the first imperial examination in Luoyang, the sacred capital, and called a large number of scholars to take the imperial examination. Su Qianxun, the son of the Suzhou governor, went to Beijing to take the exam under the escort of his retainer Zhao Guotai.
Seeing that the day of the imperial examination was approaching, when the two of them traveled to the eastern suburbs of Luoyang, heavy rain fell for several days. The bridge across the river was washed away by the flood. The two had no choice but to brave the rain and enter the Lost Manor on a nearby hill to rest.
It happened that a bizarre murder occurred in the manor two days ago (the eldest son of the manor, Mi Hang, was killed), and the owner Mi Yuan was asking Su Qianxun to solve the case.
Su Qianxun met a woman he fell in love with at first sight at the Lost Manor. However, this woman was not only inextricably linked to the murder, but was also Mi Yuanzheng's third wife, Zhang Weiai...
While Su Qianxun was searching for the murderer, another murder occurred in the manor that night...
