Feeling unfulfilled as a woman, and having just passed her 29th birthday, Carol quits her job as Bob's receptionist. After having been gone for a while, Carol suddenly shows up at one of Bob's group-therapy sessions and creates a situation in which Bob finds himself more of a patient than a doctor.
