S3, E1: 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 (Oliver Platt). Dr. Halstead (Nick Gehlfuss) and Dr. Manning (Torrey DeVitto) work on a heart wrenching case that forces them to examine their own matters of the heart. Though Robin's (guest star Mekia Cox) brain tumor was removed and she is discharged from the rehabilitation center, Dr. Rhodes (Colin Donnell) remains on edge that her problems are not quite resolved. Meanwhile, Rhodes gets blindsided by his colleague Dr. Bekker (Norma Kuhling), Maggie (Marlyne Barrett) sticks up for a patient and Dr. Choi (Brain Tee) and April (Yaya DaCosta) try to navigate their new working relationship.
