Shen Yan is a herbalist who is hidden in the market. With his precise cooking skills, he accidentally helps the top class Lu Yan solve his hidden problem of insomnia all the time, and is forced to step into the mixed entertainment circle. He accepted the clever Wen Xu as his apprentice, and originally wanted to make medicinal diet in a low-key manner, but he encountered strange things one after another: top-notch studio props were tampered with, co-stars suddenly suffered from food poisoning, and even his own medicinal diet formula was secretly leaked.
The cautious Shen Yan noticed something was wrong and followed the clues. He actually implicated the resources of the bully male partner Zhao Lei and even discovered that a mysterious agent was secretly monitoring entertainers in the entertainment industry. The two masters and apprentices work together, using medicinal food as an entry point, to work their way through the glitz and glamor of the entertainment industry, while dealing with open and covert attacks while looking for traces of the mastermind behind the scenes. This seemingly peaceful journey to health is already full of invisible traps.
