They experience life and death as they race against time to save patients. In their quest to become physicians, have they ever stopped to think about what their mission and limitations are? Neurosurgery trainee Cheung Yat-kin does not have time for love – he has to work hard to support his younger brother, who is paralyzed from the waist down, to study overseas. His life is his work, until he meets Fan Tze-yu, who is also a reputable doctor and whose father is a well-known physician. Deeply attracted to Yat-kin’s talent and personality, Tze-yu is not hesitant to express her love for him from the start. But before Yat-kin can make up his mind on whether to accept her, the news of his younger brother’s death comes, causing him to become a totally different person.
Neurosurgeon Cheung Yat-Kin marries fellow doctor Fan Tze-Yu and the two are happily living together, expecting their first child. However, when Tze-Yu is diagnosed with a tumour, her pregnancy becomes medically unsafe and, much to her dismay, Yat Kin doesn't want her to go through with childbirth. This causes a dangerous rift between the two, one that love alone can't bridge. But before the once-happy couple can focus on their marital problems, Yat-Kin also has to contend with pathology specialist Lok Man-Sang, a new arrival to the hospital who simply cannot go without disagreeing with Yat-Kin, and who also gets involved with Heung Chin-Yi, an internal medicine doctor nearly 20 years his junior with her own heartbreak to deal with. Between an unwanted power struggle, the slow disintegration of their marriage, and the small matter of saving lives, Yat-Kin and Tze-Yu have to figure out how to bring their flat-lining marriage-and love-back to the operating table.
When the President's only daughter, Liu Xinping, checks into a hospital for her chemotherapy treatment, the head of internal medicine and the head of surgery become core members of the President's medical team. Both men plan to use this opportunity to prove themselves as the best candidate for the position of hospital director. As a result, the two men appoint rival surgeons to attend to Xiuping's surgery.
