Monk and Sharona go on a short plane trip to visit Sharona's aunt. Monk is phobic about air travel. Don't blame him. White knuckle moments abound, with annoying children, talkative seat neighbours and worries about the survivability of sitting in the seat (rather than other seats). Meanwhile Sharona is taken with a celebrity sitting in first class. Oh, and meanwhile, of course, a passenger is a murderer who killed off his wife and someone else is murdered mid-flight. No one notices except Monk. It all comes down to a few clues that only he notices. Honestly, you'd think every second person was a mass murderer. Forget the murder mystery, just appreciate the bad plane ride, and how Monk reduces the stewardess to drink.
