Siji Changliu Hospital, in the corner of a busy city, figures in white intersect here. Du Yucheng, the attending general surgeon, constantly ridicules himself to resolve medical troubles, medical errors, workplace infighting, and the pressure of difficult cases. ICU head nurse Lin Yuqian is happy to be the team's "joker", but she shoulders the heavy responsibility of the nursing team alone. Director of the Department of Cardiology, Han Zhiheng, is calm and strict, and has extremely high standards for his profession and team. He often competes with Du Yucheng on surgical plans but also sympathizes with each other. Emergency intern Zhao Ziyao ushered in the most testing period of his medical career, and gradually grew up in the face of life and death, and doubts. Jia Moli, who works in the laboratory department, is taciturn and demanding on accuracy, and uses reason to balance emotions. Sheng Suwei, from the Department of Psychology, is good at using humor and insight to unravel the knots of the doctor-patient team, making the inner struggle clear on the surface. Each of the six people intersects online and offline. In the "constant crisis" in the hospital, there is either comedy or warmth, and they grow up with the conflicts of family, friendship, love and self-rescue. In the daily life of laughter and tears, they try to find their own salvation and rebirth.
