Let the Missing Children Return Home Early

Ten years ago, police officer Lu Zheng's sister was abducted at a temple fair. With clues lost and his family shattered, he swore to become a 'light seeker' and dedicated himself to anti-trafficking work, focusing on cold cases. In 2024, a case of a missing girl in a remote mountain area leads to a cross-border 'dark web' trafficking ring operating along the southwestern border. Under the guise of 'adoption,' they sell children, force them into begging, and even erase their identities. Lu Zheng assembles a special task force: forensic expert Su Wan, who traces DNA from old items; cyber police officer Chen Mo, who cracks encrypted dark links; and a returning undercover informant. They traverse isolated villages and cross-border black markets, battling ruthless traffickers, clan cover-ups, corrupt protectors, and life-threatening dangers. Behind every file is a family's tearful wait; every rescue is a life-and-death struggle against darkness. When clues about his long-lost sister resurface, Lu Zheng must choose between family and justice. In the depths of darkness, someone always lights a lamp to seek the light; on the long journey home, every child deserves to return.
