Deep in the vast Yin Mountains at the junction of western Hunan and southeastern Guizhou, there is an ancient legend about the "Goddess". They are not Taoist priests, not monks and nuns, but a group of folk women who can communicate with ghosts and gods and specialize in unraveling evil spirits.
Lin Wan, a 24-year-old rural female teacher, was adopted by her grandmother Chen Apo since she was a child. Grandma is the last goddess in the Yinshan area, but she strictly prohibits Lin Wan from contacting any yin and yang things. She only hopes that she can study and become talented and stay away from her fate. However, a strange "Ghost Crying Marriage" incident pulled Lin Wan back into the world she was trying to escape from.
In order to save a young girl who was targeted by a "ghost", grandma Chen Apo fought with an unknown entity entrenched in Soul Burial Ridge, but her efforts were exhausted. Before she died, she handed Lin Wan a black wooden plaque engraved with the ancient character "Lu", and also handed over the cause and effect of the Yinshan Goddess lineage that had not been solved for hundreds of years.
