Ghosts and gods are only masks. The human heart is the real abyss.
Mo Chen, a former painter, is forced into a baffling case involving a blood moon. Faced with a series of strange tales of “crimes committed by ghosts and gods,” he joins forces with a female physician, a wandering hero, and a defrocked Taoist priest to establish the Mo Family Detective Agency.
Using reason as their brush and science as their ink, they crack crimes deemed “impossible.” As the fog surrounding eight bizarre cases is gradually dispelled, a vast organization that manipulates people in the name of “destiny” finally emerges.
