In this season's opener, an out-of-control Mercedes smashes through a wall of the clinic; Molly, a mentally disturbed and dellusional young woman, holds Syd (Melina Kanakaredes) at gunpoint because she thinks she kidnapped her baby; and Helen contemplates a new career, away from the clinic. Meanwhile, Joanie hires Doug Dog Boy Boyce to help her out at the Barkery.
