Zhou Tieshan, leader of the rebar crew, leads his brothers to make a hard living on the construction site, but is humiliated over a box of spoiled rice and completely breaks ties with the unscrupulous fast-food boss Li Wancai. He brings thirty workers into the failing Xiaohe Fast Food Stall, and also teaches the rules of "clear pricing and settling accounts on delivery" to stall owner Lin Xiaohe. As business gradually thrives, Li Wancai lowers prices, spreads rumors, cuts off water and electricity, and even sabotages the generator on a cold wave night, leaving four hundred workers facing a food shortage. Zhou Tieshan leads everyone to build stoves with red bricks, make fires with coal, and carry water on their shoulders, guarding hot meals and also guarding the dignity of laborers.
