Meredith, isobel Steven and Chris Ding Na Yang were students yesterday. Today they are doctors. If they can survive seven years of purgatory in Grace Hospital, they can become qualified surgeons. However, in front of the trio, they have to deal with not only hard internship training, but also jealous boyfriends and morbid parents, one-night stands and housing crisis. Faced with many difficulties, they had to rely on each other.
