In the shadows of bustling cities, evil thrives in the strangest ways. Chen Mo, a taciturn female undertaker in the city's funeral home, is actually the last descendant of the ancient tradition of "Burying the Criminal". She relied on the powers of "Soul Purification Hand" and "Observation of Remnant Thoughts" to read the last murmurs of the deceased on the cold corpse, and sense the marks of death that cannot be explained by science. She firmly believed that her mission was only to appease the souls of the dead, until she met the city detective Lin Xiaotian.
