The peaceful city of Portland, Ore., boasts one of the highest safety ratings in the country. Here, even swimming alone is illegal. But accidents will happen, and when they do, it's the doctors and nurses of Legacy Emanuel Hospital who come to the rescue. The patients here include a 69-year-old shot in the stomach by his wife, a woman suddenly paralyzed because of a blood clot, and a confused patient who is wandering the hospital naked.
