Twenty years ago, the Chen family suffered a monstrous false accusation, and many lives fell. Song Huaimin used this to build a massive business empire, and Lin Guifang's biological son, Chen Wei, unexpectedly turned out to be a participant in that year's event. Twenty years later, Lin Guifang returns with clues, determined to investigate the sealed old case. Layer by layer, she gathers evidence, unmasks Song Huaimin's disguise, and exposes the interest entanglements between him and his son. Inside the courtroom, she presents all the evidence, letting those involved in the case that year face the judgment of the law. As the gavel falls, Song Huaimin's reaction before his death brings to light a startling hidden story—he was merely a pawn on the front stage. The true mastermind has already cast their gaze toward the granddaughter by Lin Guifang's side.
