Bold and ever-capable trauma fellow Dr. Connor Rhodes (Colin Donnell) is the newest doctor on staff at Chicago Med. Dr. Will Halstead (Nick Gehlfuss), chief ER resident, is an Ivy League-trained trauma surgeon and brother of CPD’s Det. Jay Halstead (Jesse Lee Soffer). Halstead practiced medicine in New York for 10 years before returning to his Windy City roots and is the epitome of reliability, both in and out of the hospital. Dr. Daniel Charles (Oliver Platt), Med’s Chief of Psychiatry, possesses remarkable insight into his patients and is off-the-charts intelligent in all subjects but his own personal life. Sharon Goodwin (S. Epatha Merkerson), the venerable head of Chicago Med, expects the very best from her people as she balances the tremendous pressures of running the city’s largest hospital, and always with a sense of humanity that allows her doctors to provide the very best care possible. Dr. Natalie Manning (Torrey DeVitto) specializes in emergency pediatric medicine and is completely focused and dedicated to her patients, despite being in the third trimester of her pregnancy. Dr. Ethan Choi (Brian Tee) found his calling in medicine while serving as a Navy flight surgeon. Currently on away rotation, he is a tireless yet impulsive doctor who is well-versed in infectious diseases. Fourth-year medical student Dr. Sarah Reese (Rachel DiPillo) is a super proficient overachiever who has never struggled at anything academically, but who may soon find that, for the first time, she’s in over her head. April Sexton (Yaya DaCosta) is a smart, bold and intuitive ER nurse who is the lifeblood of the emergency room. She loves the action inside the hospital and is as loyal as they come. Together, they will confront Chicago’s most critical medical cases and challenging ethical dilemmas with courage, compassion and state-of-the-art treatment. Inspired by ripped-from-the-headlines cases, "Chicago Med" will weave cutting-edge medicine with the personal drama that comes with working in such a high-intensity environment.
