Tom Selleck stars as Frank Reagan, the New York Chief of Police. Frank's eldest son Danny is a seasoned detective, family man, and Iraqi War vet who on occasion uses dubious tactics to solve cases.

Baltimore's renewed police commitment brings fresh recruits to Daniels and McNulty, starting with Carver. Facing a new political challenge, Carcetti is forced to make dangerous political deals.

After an EMT is shot and killed, Danny and Baez work to determine who is behind a chain of ambulance robberies. Also, Frank defends New York's homeless community after the mayor puts a new law in place; Erin tries to put away a violent perp after a judge rules he's not guilty, and Eddie offers to help Jamie pay off his student loans.
