With a Polo tournament in full swing in the Hamptons, HankMed's on hand to treat a Polo Team Owner who won't quit playing despite his condition. Also, Divya deals with the realities of dating and Evan frets about an impending meeting of the in-laws.

While HankMed treats a high-strung student for a bad case of nerves, her easy-going romance novelist mother falls ill as well and Hank must race to diagnose the two seemingly unconnected conditions.
