Su Nian is the youngest partner at Mingli Law Firm. Every court trial is like a precision surgery, until she takes over a seemingly simple medical dispute case and discovers that behind the defendant's hospital is the money laundering chain that Lu Chen is investigating. The two went from court battles to secret games, with Zhou Min secretly manipulating evidence, Chen Yuan intervening in the proceedings under pressure, and Lin Xiao being threatened for private investigation. When the gavel is about to fall, Su Nian discovers that the case of his parents falling off a cliff overlaps with the mastermind behind this case - the real battlefield is never in the courtroom, but between the tampered files and the silent truth.
