Diana Lochkhart and Celeste Seranno face a major problem when their key witness in a law suit commits suicide. Diane is representing the passengers and Celeste the crew members who all died in a plane crash. Their witness was going to testify that the aircraft manufacturer knew there was a fault with the deicing system and didn't correct it due to costs. The only solution they have is to call in Colin Sweeney, someone they know well and whose company financed some of their work. Sweeney wants out of prison in return for his testimony. The SA's office wants him to wear a wire to get evidence on a white supremacist who is ordering hits from inside prison. Meanwhile, Eli is working hard to get Peter the keynote address at the Democratic convention. Alicia is under pressure to hire David Lee's niece and she has to deal with daughter Grace's choice of friends.
