Lin Jichuan, Ji Xuanzhou and other lawyers with their own unique skills competed fiercely for cases in the city's top law firm "Yunzheng". Everyone makes repeated choices between practical interests, professional ethics and inner beliefs. The main lines of the three major cases - disputes over chaebol capital, major criminal injustices, and multiple labor disputes - are intertwined, gradually intertwining the fate of everyone. Bai Shiyuan's family secrets become a hidden thread in the law firm's game. Entrepreneurial partner Luo Jianyu made great strides to promote the listing of the law firm, and the collision with the idealistic young people caused an uproar. Intern Xiao Zhishen grew up in the case chain and became the seed of conscience and change. Through the ups and downs of cases and emotional entanglements, the lawyers each ushered in the path of mental maturity, choice and redemption, and finally faced a final trial together that could change the fate of the law firm and their lives.
