Meet Meredith Grey, a woman trying to lead a real life while doing a job that makes having a real life impossible. Meredith is a first year surgical intern at Seattle Grace Hospital, the toughest surgical residency program west of Harvard. She and her fellow first-year interns were students yesterday; today they're doctors in a world where on the job training can be a matter of life and death. Such is the world of "Grey's Anatomy," ABC's midseason medical drama about young people struggling to become doctors and doctors struggling to remain human. It's a world filled with intensity, humor, sex and pain, in which the interns discover that neither medicine nor relationships can be defined in black and white -- real life only comes in shades of grey.
