A charming young doctor puts a member of the surgical team in an awkward position at work; Dr. Glassman suggests that Dr. Shaun Murphy meet with a therapist.

The team at St. Bonaventure needs to quickly discover the truth behind a young college student’s unexplained injuries before his condition worsens. Meanwhile, after losing his most prized possession, Shaun’s distraction during a surgical procedure may end up risking more than just his job.

Dr. Shaun Murphy and Dr. Alex Park treat two patients who collapse at the local airport and whose symptoms point to an infection that may become airborne. The staff races to contain the infection before it spreads to the rest of the patients in the ER, resulting in a hospital quarantine during the holidays.

Dr. Shaun Murphy is desperate to join the team on a dangerous procedure involving a patient’s tumor removal. However, having been removed from the surgery team by Dr. Jackson Han, Shaun must use his talents to help figure out the cause of an infant’s injuries.
