Ellen has to make another life-changing choice when she performs emergency surgery in her own home. Meanwhile, Duncan demands answers when Archer tells him that an innocent person in their plan has become a victim.

When Ellen's sister, Lauren, shows up unexpectedly at their house intending to stay, Duncan forces Ellen to get rid of her without making it look suspicious. Meanwhile, when the secret service calls Ellen in for questioning again, she must play it cool when Duncan is there to help do the questioning.

Ellen and Brian agree that they need to take down Duncan to have any chance of escaping, so she sneaks away to see a man who has previously helped her solve problems. However, unbeknownst to her, this man has ties to Duncan. Meanwhile, Archer's accomplice plans to reveal to the Assistant District Attorney information about a murder Archer committed.
