An accident gave Li Ran the gift of yin and yang eyes, and he has been involved in various supernatural events ever since. In order to get rid of the trouble, he convened the gangster Bao Zhiguo, the mysterious female assistant Xu Manman, and the spiritual world veteran Song Lao to form the "Gang of Four". In order to balance the yin and yang and resolve the grievances of humans and ghosts, he began an ups and downs folk ghost exploration journey. They humored each other and helped each other. While resolving supernatural incidents, large and small, they explored the deeper secrets behind the many innocent souls headed by Bai Rulan. As the mystery is revealed step by step, they are also drawn into the vortex of cause and effect among ghosts. After the ultimate mystery is solved, should we let go of resentment or be reincarnated and redeemed? Family, friendship, love, destiny and conspiracy will eventually end in this reincarnation journey that coexists with humor and horror.
