Code Black is a high-octane medical drama set in the busiest, most notorious emergency room in the nation: Angels Memorial Hospital. The series centers on the residency director, Dr. Leanne Rorish, who is known for her unconventional and aggressive methods in the trauma bay. The term 'Code Black' refers to a situation where the hospital's resources are so overwhelmed by the number of patients that the staff cannot provide adequate care to everyone, forcing them to make impossible life-or-death decisions under extreme pressure. The show follows a group of first-year residents as they navigate the chaotic environment, learning to balance their personal lives with the grueling demands of the ER. As they work under the mentorship of Dr. Rorish and the seasoned nursing staff, they face ethical dilemmas, personal tragedies, and the constant struggle to save lives in a system pushed to its absolute breaking point.
