A string of bizarre murders shatters the city’s peace. The victims seem to have nothing in common, yet countless hidden connections link them. Lin Yu, a former prosecutor whose career in the justice system ended in failure but who still believes in justice, resolves to seek the truth on his own after his close friend dies under strange circumstances.
As his investigation deepens, Lin Yu discovers that the cases are connected to a mysterious organization. In the name of judging evil, it carries out vigilante punishments. Its members use online platforms to expose information about so-called “sinners,” stir up public outrage, and then carry out deadly acts of revenge.
As he pursues the truth, Lin Yu faces obstacle after obstacle. The mysterious organization closes in, determined to stop him from exposing the truth. The police, too, are skeptical of his investigation because of the lack of evidence. Meanwhile, Lin Yu must confront his own inner turmoil. His past failures within the justice system have left him questioning how justice can be achieved.
Lin Yu refuses to give up. With keen insight and unyielding perseverance, he painstakingly pieces together the clues. Every step closer to the truth brings greater danger, and his family and friends are drawn into the dark maelstrom as well. Yet Lin Yu remains steadfast in his convictions, struggling to choose between the law and vigilante justice, between justice and revenge. Will he ultimately expose the mysterious organization’s true face and ensure that real justice is served?
