Fan Chen, a talented food critic with an absolute sense of taste and super-amnesia, has an arrogant and calm personality. He regards ingredients as data and cooking as a chemical experiment. His brain is like a sophisticated supercomputer, which can instantly analyze the proportion and origin of each spice in the dish. However, a sudden car accident allowed him to accidentally awaken an incredible "gold finger" - soul exchange. As long as he tastes someone's hand-made dishes that contain strong emotional fluctuations, his consciousness can temporarily reside in the other person's body and read the secrets deep in his memory.
In this bizarre food world, Fan Chen discovered that there was an unknown truth hidden behind every famous dish. In order to explore the mystery of the theft of the top ingredient "Asparagus Ginseng", he was forced to be involved in a conspiracy led by the dark culinary world. The villain is not a human being, but an "evil superpower" - the "Shadow of Gluttony" - that can parasitize in the chef's body and amplify his jealousy and greed. The possessed chef will cook irrational dishes, causing diners to riot. Fan Chen must use his academic master's wisdom to sneak into the suspect's inner world through soul exchange, find clues in the maze of taste, solve puzzles about human nature and redemption, and finally prevent the "Shadow of Gluttony" from swallowing the entire city.
