Ye Ling'er wholeheartedly protects her young brother, A Bao, hoping to find their father who is far away serving as a soldier at the frontier border. The elders in the family consistently favor the offspring of the eldest branch, leaving Ling'er and her younger brother uncared for over a long period. By a stroke of luck, Ye Ling'er possesses a portable storage space, stockpiling various supplies in advance, packing her luggage, and embarking on the journey heading north. Along the way, she encounters Head Guard Lin, Uncle Xu, and others who assist her northward all the way. Relying on her courage and wisdom, she seeks out her path step by step, only hoping the family can be reunited.
