As Jane and the team investigate the poisoning death of the "queen bee" in a country club, they discover a community full of secrets - including love affairs and drug abuse.
An ever present butterfly prompts the question on what could have happened different as Turk looks for his lucky do-rag for surgery, and Elliot tries to find a lost stuffed animal for a child needing a bone marrow transplant.
When Turk saves a man's life at a taco stand, he tries to keep his ego in check as Dr. Cox takes all of the credit.
