When Danny and Baez suspect a little girl might be the victim of a kidnapping, the girl's mother denies it, but her story doesn't add up. Meanwhile, Frank pays a visit to a priest, a counselor to the NYPD, who was arrested on a DUI charge.

Danny's world is rocked when Robert Lewis (Michael Imperioli) in the Attorney General's office obtains new evidence against him in the self-defense shooting case of serial killer Thomas Wilder. Also, Jamie and Eddie respond to a car crash involving a high-profile drunk driver, and Frank is asked by Grace Edwards (Lori Loughlin), the wife of a slain police officer, to keep her only son out of the police force.

Frank questions whether a run-in with community activists was an accident or a setup. Also, Jamie strives to rely less on Frank's input to makes decisions, Erin helps Anthony protect his daughter and ex-wife from a dangerous psychiatric patient, and Danny and his neighbor size each other up when they learn their kids are dating.

The team investigates the 1958 murder case of a newlywed Ivy League graduate, Julian Bellowes, who spearheaded the lucrative concept of developing suburban communities with affordable housing outside of Philadelphia. New evidence indicates he may not have been killed where his body was found.

In part two of the two-part season finale, as the team intensifies their quest to find the person behind the 2005 slaying of a female cadet, the stakes of the case are raised when the unknown killer commits a shocking act against Rush designed to thwart the investigation.
