Song Zhiyu was hired by the rich woman Qin Ruolan to cook leftovers for a banquet in the name of "humiliation", and faced picky, mean and cheapest ingredients every day. She used kitchen leftovers to make amazing sunflower chicken bone soup, fish scale jelly and fried golden grains from overnight rice. The anorexic Qin Ruolan made an exception and ate three bowls in a row. When Qin Ruolan discovered that Song Zhiyu could use sour tofu to make the best fermented bean curd, she switched from exerting pressure to begging for cooperation - but assistant Jian Wei secretly photographed the recipe, and blogger Lu Shiqian revealed the Qin family's past, and a business war and human nature battle over the secret recipe for leftovers began.
