Mark Greene has a rough day with several relatives who are less than happy with the care being provided to their relatives but when he is savagely beaten in the men's room, he has no idea who is assailant might be. A new resident, Dr. Anna Del Amico, joins the ER team. Benton and Carter get to assist on a kidney transplant but unlike the other surgeons, Carter is more interested in the patients than the surgical procedure.
