Su Yan, an unemployed programmer, was forced to inherit the community canteen that was on the verge of bankruptcy, but was bound to the "Shan Hai Jing Food System".

From word-of-mouth among neighbors to online live broadcasts, from food monopoly to legal siege, Su Yan holds the magical seeds in hand and guards the kitchen, setting off a warm war about the nature of food.
