As Mindy and Casey adjust to their new life in Haiti, their blissful time is cut short when Mindy suddenly falls ill and is airlifted back to New York. Meanwhile, Schulman & Associates welcome their new resident OB/GYN Paul Leotard, a charming, former model who also happens to be a sex therapist and offers sex therapy advice to Danny and Christina.

After returning from Haiti, Casey has an identity crisis and thinks being a disc jockey might be his new calling. When Mindy and the office go to a music festival for their "work retreat" to see Casey perform, the substance-filled surroundings lead to a series of disasters. Meanwhile, back in New York, Jeremy hires a new doctor, whom Mindy doesn't particularly like after he saves the day during an emergency delivery.
