Despite a generous offer from Inspector John Jarvis, Oliver isn't interested in extending his contract as Acting Staff Sergeant. He's thrilled to be going back to the street. But Oliver's day takes a serious turn for the worse when his daughter Izzy shows up unannounced at the station, and when he learns Professional Standards is arriving early for Duncan's dismissal hearing. Oliver and Andy do some crash-course prep, but both are rendered speechless when Duncan presents incriminating new evidence against Andy. Cornered, Oliver finds himself making the exact kind of professional deal he never thought he would be capable of making.
