Zach makes a discovery that leads Alicia and Cary to believe that the Lockhart/Gardner firm is spying on them; Will helps one of Alicia's former clients; Clarke Hayden (Nathan Lane) offers financial advice to Florrick/Agos.

As Florrick/Agos move into their new offices, Alicia attempts to block the deportation of an undocumented immigrant before he is sent to Mexico, where a cartel has threatened his life. Also, Marilyn is concerned about the ethical ramifications when Eli reconnects with Natalie Flores, and Robyn tries to be more like Kalinda.

Alicia represents a band suing a TV show for copyright infringement, but the simple case becomes psychological warfare when Will joins the opposing council and uses his knowledge of Alicia’s strengths and weaknesses against her.
