Erin and Frank clash over new legislation from the district attorney's office that undermines Frank's policies. Also, Erin is at odds with Governor Mendez over questionable sex-trafficking laws; Danny risks his badge to protect a friend from losing his; and an accident on the job forces Jamie to question whether he's ready to be a sergeant.

When a video surfaces of officers partaking in a clear case of entrapment, Frank focuses on finding the cop who leaked the video. Also, Eddie retaliates against a co-worker who is pranking Jamie; Danny and Baez investigate the murder of a tabloid writer who worked in the hip-hop scene; and Erin gives a high-profile case to a young ADA under her tutelage.
