He Jing (Tong Liya) entered the critically ill pregnant and lying-in women rescue center of a large hospital in the provincial capital to study. On the first day of her appointment, she used her own native methods to rescue a critically ill parturient, which made Xiao Cheng (Wang Yaoqing), director of obstetrics, and Wei Lili (Qian Jie), deputy director, realize the huge potential hidden in this ordinary-looking girl. Xiao Cheng grew up in a superior environment. After returning from overseas studies, he entered the hospital as a chief physician. Although he was skilled in medicine, he was very unaccustomed to the domestic medical environment, so he had a lot of conflicts and contradictions with He Jing. However, as time went by, He Jing's kindness and persistence gradually moved Xiao Cheng, and a naive love arose between the two. In the small department, scenes of joys and sorrows were staged.
