After reading about her struggle online, Evan reaches out to a woman with a mysterious illness in the hope that Hank can finally give her a diagnosis. Paige and Russel's professional lives take an unexpected turn, and their new client could be a goldmine or a dangerous problem — especially when he becomes a HankMed patient. While Evan and Jeremiah realize they'll have to go to battle with Symphony if HankMed is to survive the summer, Hank's watchful eye on Emma helps him win back a former patient.

Hank and Divya treat a professional Hamptons house-sitter who never wants to grow up, and Jeremiah gets closer to Viviana when he treats her friend, a burlesque dancer. Paige makes a discovery that could complicate her new business with Russel, and Emma becomes a tipster for the Hamptons' hottest gossip site.
