It's Super Bowl XXXV in Tampa, and the city is packed — the hotels are full and the roads are crowded, which means more trauma cases for the only Level-One trauma center along the west coast of the state. Tampa General is a teaching hospital associated with the University of South Florida, located on Davis Island and across from the downtown area. In this episode, the emergency staff handles a heavy patient load, including: two separate mothers involved in car accidents with their young children — one mother left paralyzed from the shoulders down; a cerebral palsy victim burned after falling into hot water; a girl suffering from grease burns; and a teenage girl whose truck skidded off the road into a concrete culvert.

Originally a major crossroad of the old west cattle trails, Dallas is now a high-powered center of the world's financial, technology and petroleum industries.

New Mexico is full of mountains, plateaus, rivers and breathtaking sunsets. Vast and wild landscapes border fast-growing cities, and intricate webs of highways cross thousand-year-old rock carvings. Albuquerque's University of New Mexico Hospital is the only Level-One Trauma Center within 400 miles. The more-than 50,000 patients who walk or are wheeled into its emergency room come from southern Colorado, eastern Arizona, the Navajo nation and right around the corner, and their traumas range from minor skin abrasions to serious internal injuries. In this episode the ER team at Albuquerque's University of New Mexico Hospital faces: a young woman suffering injuries after being trapped under her car for 12 hours; a toddler who has lodged a popcorn kernel in her ear; a combative young man injured in a high speed accident; a man rushed to the hospital whose condition deteriorates as the minutes pass; and the victim of an accidental gun shooting.

One hundred miles northeast of New York City on the Long Island Sound lies the busy port city of New Haven, Connecticut.

Serving the urban, suburban and rural communities, the E.R. team at Yale-New Haven Hospital faces such trauma cases as multiple car crashes, farm equipment accidents and inner city gangland shootings nearly every day.

Now, although it still holds its place as one of the largest agricultural areas in the country, the city has been transformed into a small metropolis with more than 1.5 million residents.

Seven of the nation's major highways pass through downtown Indianapolis, bringing half of the country's population within a day's drive. Those open roads have paved the way to a host of urban problems … and forever changed the once-wholesome character of this heartland city.
