Suits' eighth season ushers in a new era for the company after Mike Ross and Rachel Zane leave. The newly combined company, now known as Zane Specter Litt Wheeler Williams, is directed by Harvey Specter and Robert Zane. Their divergent leadership philosophies cause conflict among the partners as well as amongst them. Samantha Wheeler, a determined and gifted attorney hired by Robert, is introduced in the season. She establishes herself right away and builds intricate bonds with Donna, Harvey, and the other members of the team.

The competition between Samantha Wheeler and Alex Williams for the title of name partner is a significant plot point. Tension from their rivalry eventually prompts Robert to elevate Samantha. As he manages his position as the firm's head and strengthens his bond with Sheila Sazs, Louis Litt, meanwhile, undergoes substantial personal development. Louis has new purpose as a result of their adventure, which culminates in engagement and the announcement that they are expecting a child.

Robert Zane is involved in an ethical scandal as the season goes on. He accepts full responsibility and consents to disbarment in an attempt to safeguard Harvey and the firm. The firm is rocked by his departure, and Harvey and Donna are forced to reassess their objectives. Harvey's realization of his genuine affections for Donna at the end of the season culminates in a passionate kiss that foreshadows a change in their future relationship.
