Monroe

Maverick neurosurgeon Gabriel Monroe goes head-to-head with his new boss when he elects to operate on a patient with a deadly vascular anomaly. Meanwhile, Jenny Bremner returns to St. Matthew's from maternity leave to find the hospital changed - and her power diminished.

Bremner and Shepherd's relationship is unravelling, and Monroe finds himself having to choose between his trainees. A woman with an aggressive brain tumor becomes one of the most challenging cases of the neurosurgeon's career.

As Shepherd and Witney reel from their liaison, Monroe finds himself without purpose after a catastrophic operation. Grave complications mean Bremner's operation on a five-year-old refugee turns into a race against time.

Monroe is busy pursuing Lizzie counseling Shepherd when an awkward, violent woman arrives at St. Matthew's with a deadly cerebral aneurysm in tow. The neurosurgeon calls on Bremner to help save her life.

Monroe and Bremner attempt parallel miracles: curing the epilepsy of a middle-aged woman and accomplishing the heart transplant of a teenage girl. It's just a pity their love lives are about to come unstuck...

Nick's stag party is ruined when a lethal traffic accident brings the whole team into the hospital. While the hospital's facilities are stretched to the breaking point, Bremner and Shepherd reach an agonizing crossroads in their relationship.
