In a city of love and prosperity, a city of lost hope and premature death, veteran detective Hei feels it all: the hurt, the helplessness, the horror. When his father-in-law, the billionaire benefactor Kim, is gruesomely murdered in his palatial mansion, he enlists the assistance of his former partner turned private detective.
Unfortunately the movie Confession of Pain is not yet available on HBO Max.
