Steven "Kelly" Grayson has seen the best of us at our worst. When hearts stop working, when blood alcohol levels exceed limits we shouldn't contemplate, when bodies are extricated from car wrecks, he's been there to pick up the pieces, save our lives, and watch us slip away. En Route is an unflinching look at the heart of a paramedic and the profession that shaped him. Grayson's touching stories of life and death and the hilarious ones of times in between are here to give us an insight of what happens after we call 911, the ambulance doors close, or even what happens inside the ER when the nurse shows the family to the waiting room.
