A Ye discovers a phone hidden among old belongings, containing a recording of someone pleading for help, and follows the clues into the abyss. Missing children, secret crimes, and a buried past surge out from the cracks in the darkness. He ventures through the shadows of freight depots, bloodstains at the ends of alleys, sobs on school grounds, and blades flashing across the internet, weaving between bizarre celestial phenomena and traps made of money. He discovers that every incident is tied to a single dark thread. At its end lies a hypocritical "philanthropist," a criminal network spanning decades, and reflections of countless shattered families. This journey through the shadows is all to make sure that one day, the cries buried in the darkness will finally be heard by the sunlight.
