Noh Sung-Jae, now a police officer, returns to his hometown of Maerim-myeon after being assigned there. He thought he simply had to adjust to his new life, but forgotten memories, like the deaths of his parents, begin to surface, tormenting him. Meanwhile, a "body amputation incident" linked to his parents' cult begins to repeat itself, and Jun-Hyeok and Hyun-Tae, who are hovering around Sung-Jae, become increasingly suspicious.
