Chef Zhou Zheng was kicked out of his job because he insisted on scientifically improving cold noodles, and he could only make a living by setting up a stall in an old alley. Su Tang, a gold medal judge from the Food Association, accidentally tasted his bowl of iced hot and sour cold noodles and was so shocked that he immediately proposed to cooperate in the competition. Unexpectedly, this bowl of noodles not only caused the president of the association to kneel down and beg for brand authorization, but also brought up the old grudge of the master's tampering with the secret recipe, the mystery of Su Tang's father's suicide due to vegetable fighting, and the secret manipulation of traditional food by provincial capital forces. Zhou Zheng used a bowl of cold noodles to stir up the undercurrent of the entire food circle, and Su Tang had to choose between him and revenge.
