When lives are on the line, the dedicated doctors, nurses, and staff of Chicago's busiest trauma center are the ones to trust. In the engrossing second season of Chicago Med, big changes put the ER on an emotional collision course. A slew of both professional and personal issues-from legal setbacks to romantic entanglements, illnesses, and the elusive work-life balance-threaten to affect those trying to maintain cutting-edge medicine with care and compassion.

As the courageous team of doctors, nurses and staff of Chicago Med deal with the pulse-pounding pandemonium of the emergency room, heart-wrenching drama impacts them both professionally and personally. With lives on the line every day, the ED team finds themselves on an emotional thrill ride through the day-to-day chaos of the hospital that gets Chicago's most difficult and challenging cases.

In the season premiere, an auto accident leaves Will and Natalie fighting for their lives. Later, the staff at Gaffney Chicago welcomes a new member to the fold: hard-partying Dr. Crockett Marcel.
