Fifteen years ago, detective Xiao Lin's sister mysteriously disappeared on the way home from school. This tragedy not only destroyed his family, but also became an indelible pain in his heart. After that, he gave up his original life track and devoted himself to the investigation of child abduction cases, becoming a "light seeker" with the mission of tracking down human traffickers.
During a seemingly ordinary investigation into a missing child case, Xiao Lin discovered that all clues pointed to a large and secretive trafficking network. As the investigation deepened, he gradually uncovered the heinous criminal methods of this organization and the intricate chain of interests behind it. The key figure in the case is actually inextricably linked to him.
At the same time, reporter Shen Xingyao secretly tracked the abduction and trafficking cases in order to expose the dark side of society. Her appearance not only brought new clues to Xiao Lin, but also gradually formed a bond between the two in pursuit of the truth. However, as the truth approaches, danger also follows.
When Xiao Lin finally got to the core of the case, he found that he had to face a cruel choice: should he stick to justice and bring the mastermind to justice, or should he choose to remain silent in order to protect certain people? And can those abducted children wait in the darkness for the light of redemption that belongs to them?
