Modern restaurant owner Lin Weiwei soul-travels to ancient times, becoming the daughter of an indicted minister exiled to the frontier. With nothing, she struggles to survive relying on her culinary skills, pushing a small food stall selling hot porridge, lamb offal soup, scallion pancakes, and skewers, making a living in the bitterly cold Yanmen Pass. Along the way of running her stall, she rescues the orphan girl Cuier, gets acquainted with the young general Xiao Tianyi, while fighting against framing by peers and official harassment, and investigating the old case of her father's unjust accusation. Food comforts the frontier soldiers; the two support each other amidst the storms, forge a world of their own in the turbulent frontier, and clear their family's false charges.
