ER follows the medical personnel and patients in the emergency room of Chicago's fictional County General Hospital. Created by best-selling author Michael Crichton ("Jurassic Park") and produced by John Wells ("The West Wing"), Christopher Chulack ("Third Watch"), David Zabel ("JAG"), and R. Scott Gemmill ("Jonny Zero"), the Emmy Award-winning series has completed fourteen seasons as one of television's highest-rated dramas.

The doctors and nurses of County's ER confront the daily challenges of a busy urban hospital, including overcrowded waiting rooms, staffing shortages, and the impact of life-and-death decisions. While they teach the next generation of doctors, each must tackle the demands of their personal lives, at times unsuccessfully.
