After Martin invites Louisa to watch the annual bird migration over Port Wenn, he treats an elderly woman whose hallucinations lead to dire consequences. Meanwhile, Aunt Sarah fumes after the reading of a will leaves her nothing and Martin must perform an emergency procedure on his young friend.

Martin is skeptical when Port Wenn welcomes an extremely friendly delegation from their sister city in Norway and Louisa visits a specialist who just happens to be Martin's ex. Also, Greg believes that he is pooping little men and Mark exhibits troubling symptoms that warrant an intervention.
