Before testifying against the pimp who had him shot, a former sex slave says Cassidy raped her when he was undercover. When Amaro and Munch go to his apartment to question him, they see Olivia exit his bedroom.
Though Brian says it's a frame-up, he goes on trial for the assault. His attorney confronts Amaro on the stand with Cynthia Mancheno, the woman he had a relationship with while undercover ten years ago. Nick learns he's the father of her nine-year-old son and Cynthia's boyfriend is using the kid to mule drugs. The squad goes undercover to get the boyfriend off the street and prove Cassidy's innocence.
