The Park family are in the airport on their way home from Hawaii when their flight is delayed for several hours. Ken has an interaction with Dr. Oz that goes awry - and then needs to get the famous TV doctor to switch airplane seats with him. Meanwhile, Allison gets overly involved in Molly's love life and accidentally breaks up with her boyfriend via text message, and Dave finds himself in a high-stakes card game with some college students. Back at Welltopia, it's "Black Monday", the clinic's busiest day of the year, and in Ken's absence, Julie is the doctor in charge, and Clark and Damona have to help her learn that thoroughness doesn't have to take forever.
Dr. Ken is a brilliant physician with no bedside manner. He is always trying to be a good doctor, as well as a good husband and dad to his two kids. However, these good intentions have a way of driving everyone crazy at both work and at home. Luckily, his therapist wife Allison is just the right partner to keep things sane.
