Even experienced colleagues are afraid of Criminal Police Inspector Chen. And it’s not just that he masterfully wields both traditional police weapons and many spiritual practices. But mainly because, on duty, he sometimes visits Hell, where he is not afraid to call to account demons of various stripes and positions who have broken the law. Chen is entrusted with the investigation of a new case. This time the girl died, but her spirit never reached the Heavenly shores and lingered somewhere at the gates of Hell instead of living in the peach gardens of Paradise. Descending into the underworld in search of the ghost of the deceased, the detective encounters the treachery and greed of its inhabitants and uncovers a cruel conspiracy against mere mortals.
