Bart takes the blame and is given a dressing down by Frank. Max, a Psych Patient, terrorizes the ED and Erica in particular. Gabrielle falls victim to the flu and has to go home. Dan takes over and becomes  Supernurse . Moral and ethical considerations come into play when the victim of a hit and run must be declared brain dead and her husband is asked by Frank and Von to consider donating her organs.
