The American thriller series "ER" tells the story of doctors at a Chicago city clinic. They urgently come to the aid of people, saving patients' lives, putting their own interests aside and not thinking about the daily heroism they perform. While fulfilling their duty, the medical staff also experience personal dramas. Doctors fall in love, break up, plot against each other, believe in the best, and... remain ordinary people, despite the challenging work and high professionalism.
