Grey's Anatomy, Season 12

April:
[opening voice-over] In trauma, we're concerned with one overriding question. How did this happen? What was the mechanism of injury? How do we see pass the mess and confusion of trauma to figure out what the damage actually is? Infinite possibilities put the patient on the table in front of you. Now you have to figure out, will they live? Will you be able to save them or are they a lost cause? Every part of a trauma tells a different piece of the story and until you look at each and every injury, you can see what went wrong.
