Single mother Chen Guilan raises her daughter Lin Xiaoman alone by running a street breakfast stall. Local thug Zhang San has long extorted protection money from her, and Chen always swallows her pride to keep her business going. Ten-year-old Xiaoman, seeing her mother pushed around and her wrists red from being grabbed, throws herself into her mother's arms and swears "Mom, I'll protect you for a lifetime". Years later, Xiaoman becomes a local police officer after studying hard. When Zhang San and his gang come to harass the neighborhood merchants again, Xiaoman shows her police ID, stops the thugs and fights for justice for her mother, finally keeping her childhood promise.
