Sacrilege (S02E01)

McNeil and Pip find themselves tasked with taking the twelve-year-old daughter of the District Attorney on a ride-along for her school project. McNeil is not particularly enthusiastic about the assignment, and things take a turn for the worse when they misplace her in the city. Concurrently, Frank adopts the guise of a priest in an attempt to extract a confession from a churchgoer, while an unexpected "nun" reveals more than just her religious attire at the precinct.
