While running from a drug deal gone bad, Mike Ross, a brilliant young college-dropout, slips into a job interview with one of New York City's best legal closers, Harvey Specter. Tired of cookie-cutter law school grads, Harvey takes a gamble by hiring Mike on the spot after he recognizes his raw talent and photographic memory. Mike and Harvey are a winning team. Even though Mike is a genius, he still has a lot to learn about law. And while Harvey may seem like an emotionless, cold-blooded shark, Mike's sympathy and concern for their cases and clients will help remind Harvey why he went into law in the first place. Mike's other allies in the office include the firm's best paralegal Rachel and Harvey's no-nonsense assistant Donna to help him serve justice. Proving to be an irrepressible duo and invaluable to the practice, Mike and Harvey must keep their secret from everyone including managing partner Jessica and Harvey's arch nemesis Louis, who seems intent on making Mike's life as difficult as possible.
5×04: “No Puedo Hacerlo” – Louis’s very lovely, very successful sister arrives at Pearson Specter Litt in search of an attorney to handle her divorce – but she doesn’t want her brother, she wants Harvey. Taken aback at first, Louis eventually agrees to try and convince Harvey to take his sister’s case. And though bad blood still simmers between the name partners, Harvey finds himself caving when Louis appeals to his soft spot for familial loyalty.
Meanwhile, Harvey plans to take the emotional complications out of the divorce proceedings by putting Esther on the sidelines while launching a typically aggressive negotiation against her soon-to-be ex. But when allegations of broken promises and infidelity surface, the case threatens to become a lot more thorny for everyone involved.
5×07: “Hitting Home” – Elsewhere, Harvey’s progress in Dr. Agard’s office is having a positive effect in other areas, as he reaches out to Donna in an attempt to start rebuilding their friendship. But friendship, like therapy, can take time, and Harvey quickly shuts down when the subject of his recent dalliance with Esther Litt comes up.
And speaking of Esther, Louis’ sister returns, looking for a lawyer to help settle a lawsuit quietly. It soon becomes clear, though, that the matter can’t be handled discreetly, causing Louis and Esther to butt heads and dredging up old sibling rivalries. However, it’s the complicated feelings that Esther’s return stirs up in Harvey, and the jealousy those feelings provoke in Louis, that could have far-reaching consequences for the firm…
8×07: “Sour Grapes” – Donna’s agreement forces Harvey to help David Fox. Alex comes to Zane’s aid on a personal venture.
9×08 – Prisoner’s Dilemma: Harvey is forced to account for his past actions and their consequences by an old enemy; Keri contemplates her future; McGann manages to find Nick.
