Song Rongshu's gray justice and Xu Yinan's white-and-black duel continue to heat up. As the cases advance in turn, the lawyers make difficult choices between friendship, love, interests, ethics and family, breaking through their psychological limits.

In the end, in a murder case involving life, death and reputation, everyone chose different paths to complete self-growth and redemption. The boundaries of the law and the perseverance of the soul have all turned into humorous but heavy human collisions.
