The heroes of the gripping TV series ER are doctors at a Chicago city hospital. They provide emergency care to patients, save lives, sometimes forgetting about themselves and not thinking at all that their day-to-day work borders on heroism. Fulfilling their professional duty, the doctors of ER fall in love, get divorced, plot intrigues, hope for the best, and... in short, they are just like everyone else, despite the hard work and a noble calling.
