Rox decides to make amends with her former step coach when she arrives to Angels Memorial with the local high school step team after a pyramid stunt goes wrong. Also, Noa pleads with Leanne and Campbell to try any other method before performing an emergency hysterectomy on a young teenage girl experiencing complications after giving birth.
In the busiest, most notorious ER in the nation the staggering influx of patients can outweigh the limited resources available to the extraordinary doctors and nurses whose job is to treat them all - creating a condition known as Code Black. At the heart of the ER's controlled chaos is Residency Director Dr. Leanne Rorish, renowned for successfully performing high-risk procedures in Center Stage, the trauma area reserved for the most critical cases.
Her four new first-year residents are Christa Lorenson, Malaya Pineda, Mario Savetti and Angus Leighton. Leanne's confidante, Jesse Sallander, is an amiable seen-it-all senior nurse who manages the residents. Also working in the ER is Dr. Neal Hudson, an excellent physician who sometimes disagrees with Leanne's 'cowboy' approach, and Dr. Rollie Guthrie, the energetic, longest-serving attending. In Center Stage, life is measured in seconds, and these heroic doctors and nurses operate with speed and skill within an overwhelmed system to treat the crowds of people who are often there for one of two reasons: to die or to receive a life-saving miracle.
