For five years, Han Song and his wife have run a small stir-fry stall at a gravel plant. As costs rise, they increase their prices from 10 to 12 yuan, provoking opposition from Zheng Xiaohu, a powerful figure at the plant, who demands that they restore the old prices. Another couple, who once received help from Han Song and his wife, brings their food truck across the road, hoping to steal their customers with low prices and using inferior ingredients to maximize profits. Unwilling to cut corners, Han Song watches his stall get smashed by a drunken Zheng Xiaohu and his men, leaving him with no choice but to seek a new way forward.
