Lu Nian, an orphan abandoned by his family, was born with a "taste resonance" golden finger - the ability to sense the memory and emotions of the maker through food. When he was eighteen years old, he was selected by the powerful "Long Yuan Group" to become the stand-in for his missing young master, Lu Han. He must imitate all of Lu Han's characteristics perfectly until the Lu family finds a true heir.
However, the first task given to him by the Lu family was to win the global food competition. Lu Nian was forced to disguise himself as a gourmet genius and use his innate taste talent to decipher top-secret recipes one after another. But every time he eats a dish, he will see the secret hidden behind it - the conspiracy in the dark culinary world, the truth about the family murder, and even the mystery of Lu Han's disappearance.
In the identity of the stand-in, Lu Nian gradually discovered that Lu Han was not missing, but was imprisoned by people within the Longyuan Group; and he was actually the only one who could find Lu Han through his sense of taste. Caught in the power vortex of the food world, Lu Nian must survive in the role of a fake young master, conquering the world with his cooking skills while tearing apart the hypocritical truth with his taste and smell. The closer he gets to the truth, the more he discovers that everything points to a surprising secret - he himself is also someone's "stand-in".
