Shen Zhiwei, a shrewd and capable trust lawyer, established a strict "marriage trust" for her newlywed husband Pei Yanshen, who became a vegetable, to protect his huge family fortune. However, when Pei Yanshen miraculously wakes up, what greets them is not tenderness, but the smoke of inheritance competition and the suspicion of cross-border money laundering hidden in the family business. Abandoning the cliché of "contract turns into true love", former couples transform into "legal partners" and rebuild trust in the cold puzzle of evidence chain. From the trap of "apparent agency" to the exercise of the "right of uneasy defense", they use professionalism as a spear and procedure as a shield to deal with cunning opponents inside and outside the court. This is not only a battle to defend huge wealth, but also a journey of justice to promote the revision of the "Determined Guardianship Law" and strive for legal protection for vulnerable groups. In the game of swordsmanship and subtle human nature in the legal workplace, see how Shen Zhiwei uses wisdom and resilience to compose his own "shuangwen" life within the framework of procedural justice.
