When Bashir Hamed finds himself at the site of a tragic accident, his medical training takes over as he works to save the wounded. At York Memorial Hospital, the staff treat patients from the accident while concerns arise about their Chief of Emergency Medicine, Dr. Jed Bishop.

When Bash and Mags work together to treat a patient with a tricky diagnosis, Mags realizes that Bash’s experience as a doctor in Syria has led to an instinct-based approach. Head nurse Claire Malone is concerned that Dr. Bishop is already working following his accident. June struggles to put her foot down with Dr. Singh concerning the needs of a patient, and Theo works to build a connection with Bash.

As Bash's future at the hospital hangs in the balance, he diagnoses a young patient with a rare disease that could have been prevented. Mags is faced with a case she cannot solve, as June tries to keep her personal life private. Meanwhile, Theo drives through the night to spend a day with his family in Sudbury.
