As the third season opens, the doctors of Chicago Med take their opinions to the extreme as they try to bring justice to the perpetrator in the shooting of Dr. Charles. Dr. Halstead and Dr. Manning work on a heart-wrenching case that forces them to examine their own matters of the heart. Though Robin’s brain tumor was removed and she is discharged from the rehabilitation center, Dr. Rhodes remains on edge that her problems are not quite resolved. Meanwhile, Rhodes gets blindsided by his colleague Dr. Bekkar, Maggie sticks up for a patient and Dr. Choi and April try to navigate their new working relationship.
