On the surface, Su Tingyun is the most inconspicuous caregiver at the mad dog shelter. He cleans the animal sheds and feeds the mutated dogs every day, but in fact, he is the real behind-the-scenes talker of this underground shelter. As an inspector sent by the Special Investigation Bureau, Qin Shixu was ordered to investigate the frequent supernatural rampage incidents in the shelter. However, as he pressed harder, he discovered that the "truth" he was pursuing was just a flaw deliberately exposed by Su Tingyun. When the superpower game at the top of the city spreads to the shelter at the bottom, two people with different agendas are forced to join forces to open a gap that belongs to them between the fangs of the mad dog and the blade of the powerful.
