Angels Memorial descends into chaos when a plane crashes into the 8th floor. Also, Noa has a car accident and it is up to Mario to save her life. Also, Willis admits to Rox that he needs her in his life and the doctors gather in court to support Leanne for her custody hearing.
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.
