Liu Niantang, the heir to the imperial cuisine, was transformed into the wife of an exiled criminal minister, and at the beginning he had to make decapitation meals for the whole camp. She backhanded a flaming lamb chop and blew it up in the execution ground, but was targeted by the prison officer Zhao Shouzhuo, who was actually an apprentice in the imperial kitchen and forced her to hand over the lost recipe. Liu Niantang used fake prescriptions to mislead Qin Huiniang who came from the capital, making the Imperial Palace a laughing stock at the banquet. He took the opportunity to catch up with the inspection censor Zhou Jingxing. A plate of food stirred up the three parties' forces, and she discovered that behind the unjust case of her husband Shen Duchuan, there was a murder case in the imperial kitchen in the past.
