In order to sign a deal for an old restaurant, real estate agent Chen Le is forced to taste the same bowl of signature noodles made by a stubborn old chef every day, but is therefore trapped in an inescapable 24-hour cycle. He must taste the memory behind every change in taste, and in repeated time, help the old man who has lost his sense of taste find his destined successor. And the final clue actually points to his best friend, a genius academic who has broken with him for many years due to his ideas. When the only exit from the cycle is for the two people who parted ways to stand side by side in front of the stove again - Chen Le discovers that what he wants to sell is not only a shop, but also a lost skill and a passionate friendship that has long since cooled but has not been extinguished.
