When a disaster called "Grey Fog" swept across the world, civilization collapsed, the earth lost its color, and even food lost its proper taste and became a bitter fuel to sustain life. In this desperate wasteland, Gu Yuan, the former three-star Michelin chef, tried to use his cooking skills to ignite the embers of civilization.
He uses the top greenhouse of a skyscraper as a refuge, uses a spatula to fight against the cruelty of the apocalypse, and uses delicious food to awaken numb hearts. Every dish is a reminder of the old days; every scent is a call for hope for the future. However, the fragrance of his food wafting in the dead world attracted not only survivors who longed for warmth, but also predators who believed in the law of the jungle.
When the instinct of survival collides fiercely with the dignity of human nature, and when a mouthful of hot soup is worth more than gold and weapons, how will Gu Yuan and his small "Cloud Canteen" build an ark of humanity surrounded by a group of thugs headed by "grey wolves"? This is a war about food, and it is also a hymn about hope, perseverance and the reconstruction of civilization played in the apocalypse.
