Xu Yuan, a graduate student in folklore, came to Luohe Town to investigate the customs of ghost marriages. He unexpectedly discovered that he had exactly the same birthday and horoscope as the groom Du Wenjin in an unfinished ghost marriage ceremony a hundred years ago. As the investigation deepened, he and local cultural director Su Yu gradually uncovered a shocking truth: the secret marriage was actually a life-extending magic spell conspired by the ancestors of the Du and Zhou families, and the resentment of Lin Wanrong, who died tragically that year, still lingers. When Du Wenjin's soul gradually awakens in Xu Yuan's body, Su Yu is chosen as the new sacrifice because of the same birthday as Lin Wanrong. The two must break the century-old curse within 48 hours, otherwise history will once again stage the tragedy of human sacrifice.
