Sun Tou Tou is an orphan in her twenties. One day, she gets into trouble while fighting injustice. Ren Xin Zheng, a professor at the University of Chinese Medicine, comes to her aid and learns her life story. Professor Ren accepts her into the TCM (Traditional Chinese Medicine) course to give her a fresh start in life. Sun Tou Tou accepts the challenge to learn under Ren Xin Zheng and eventually inherits his family's TCM practice.

Professor Ren's son, Tian Zhen, is a classmate she dislikes for causing her some difficulties. The quest of gaining knowledge is challenging enough without the added generation gap between students and lecturers. Maturing, she persists and finds herself taken with traditional medicine.

Tou Tou and Tian Zhen become closer as they learn to understand and empathize with each other. Tou Tou, her classmates, and their lecturers can now begin to follow their dreams.
