As Fitz and Ming debate the merits of their insemination plans, the doctors revisit their past entanglements. Fitz finds himself challenged by the demands of a psychotic patient. Chen is called away to Brisbane to visit his dying grandfather. And Ming comes to terms with her surprise pregnancy and what it means for her future.

It's Christmas Eve, and chaos reigns in the emergency room. Fitz contends with some hard-assed cops and a belligerent patient. It's a contentious situation that he initially handles well, but as the evening progresses he spirals out of control to a very self-destructive place. When Chen finds himself dealing with a family of a man who died in a brothel, he starts to question his own views on medicine and family. Meanwhile, though she's not embroiled in the turmoil of the hospital, Ming is confronted by her father's strange solution to her fertility problems.
