Code Black's medical staff will master new techniques and technologies in the field.
Last season, after an explosion at a presidential debate, the two wounded candidates were taken to Angels Memorial for treatment. Dr. Will Campbell threatened to report Dr. Heather Pinkney for using his prescription pad, and she threatened to accuse him of sexual harassment.
Dr. Mark Taylor returned to help Dr. Leanne Rorish find money in the budget to keep Jesse Sallander and the other nurses from walking out. Dr. Mario Savetti confronted Dr. Angus Leighton about his Adderall abuse, and ended up going to his brother, Dr. Mike Leighton, when Angus refused to admit he had a problem.
In the season premiere, Col. Ethan Willis (new cast member Rob Lowe) joins the team as part of a program in which the Department of Defense sends doctors to hospitals to teach new techniques and technologies that they learned on the field of combat.
Willis and Mike take a harrowing chopper to Malibu to help save shark bite victims; Campbell (new series regular Boris Kodjoe) has become the head of both the OR and the ER in order to save costs, causing strife between him and Leanne; and Jesse welcomes a new round of residents.
Noah Gray-Cabey, Emily Tyra and Nafessa Williams join the cast in recurring roles as new residents in the ER.
See what happens during the season premiere airing Wednesday, Sept. 28 at 10/9c.
