Linda is concerned when an elusive serial killer starts threatening her, Danny and their kids; during a hostage situation, Jamie challenges a superior officer.

The newest Speaker of NY City Council, (Whoopi Goldberg), a chronic malcontent, wants to dismantle the NYPD's "Broken Windows Policy," a position Frank vehemently opposes. Erin worries when the wife of her good friend and mentor, Judge Wilson, dies as a result of DUI, and, his sentencing suddenly runs off the rails. Linda's co-worker at the hospital has a problem with her ex-husband. Linda asks Baez and Danny to talk to the parties involved and it turns into a big ordeal. Judge Wilson takes on attorneys who dare to argue with the bench (i.e. our jobs); it may be time for a Judicial Ethics Commission Complaint. Does Erin have the balls to file one?

Jamie and Danny disagree about how to handle a reckless NYPD rookie, Marcus, who is the son of Dannys friend. Also, when Erins investigator, Anthony, gets roped into a bad investment by his cousin, she offers to look into it.

When serial killer Thomas Wilder (Louis Cancelmi) attaches a message to his latest victim that taunts Danny, their deadly game of cat and mouse becomes personal for Danny.
