Plot summary
Florrick/Agos and LG represent Lemond Bishop when he is arrested on a drug-related charge. However, the charge is based on information that could have only been known from within Florrick/Agos, and this prompts Cary and Alicia to conduct an investigation, which leads them to conclude their phones are being wiretapped by the DEA. They are in fact being surveilled, but by the NSA, which is sharing information with other government departments. Meanwhile, after Marylin submits an inconclusive report on her investigation into possible voter fraud, it escalates as the Department of Justice's Office of Public Integrity begins its own examination of the allegations and the video depicting the alleged crime, approaching Alicia and subpoenaing Will.
