When the seal of the royal tombs of the Han Dynasty was broken and resentful spirits poured into the city, psychological counselor Shen Yan took over a series of "ghost" cases. He didn't expect that the provider of the solution would actually come from the underworld - and the cold ferryman who was responsible for this was none other than his ex-girlfriend Su Qing who had been missing for five years. In order to quell the chaos of yin and yang, one uses empathy to ease the obsession of the living, and the other uses iron law to arrest the dead souls and bring them to justice. Every moment they are forced to cooperate is tearing open the scars of their separation without saying goodbye. Deep in the ancient tomb, when Shen Yan used blood as a sacrifice to seal the rift again, Su Qing finally abandoned the commandments of Hades and held his hand tightly: "This time, regardless of yin and yang, I will accompany you."
