Police officer Zhao Xiaoman from the police station received a "curious case of the century": the ancestral secret recipe of a time-honored snail noodle shop was stolen, leaving only half a bag of trampled sour bamboo shoots at the scene. He surveyed the scene with a popsicle in his mouth and compiled a list of suspects into the "Ingredients List of Snail Noodles": Uncle Wang who sells stinky tofu across the door (smell competition), the girl from the milk tea shop next door (the secret recipe crosses borders), and Lao Zhou, a sanitation worker who always comes to get free soup (the time of the crime coincides).
When Zhao Xiaoman was squatting next to the trash can to study the "angle of sour bamboo shoot tread marks", he was mistaken by a passing aunt as picking up waste and stuffed a bag of expired yuba. Holding the yuba in his arms, he had a sudden thought: "The murderer splashed the sour bamboo shoots on his trousers when he stepped on them. He will definitely go to the dry cleaners!" Unexpectedly, when he found the dry cleaners, the boss pointed at the surveillance camera and laughed until he slapped his thighs: "This thief came to do laundry in the middle of the night and spilled the sour bamboo shoots soup on his down jacket. Now the streets are filled with the smell of 'walking snail noodles'!"
In the end, Zhao Xiaoman blocked the suspect at the bus stop - he was actually an out-of-town foodie on a business trip who wanted to steal the secret recipe and open a shop back home. During the arrest, his foot slipped and he threw himself into a sack full of sour bamboo shoots. When he looked up, there was still a sour bean hanging on his face. The onlookers held up their mobile phones and broadcast live: "Look! The police uniform version of snail noodles has become a masterpiece!" This "food mystery" made Zhao Xiaoman successfully promoted from a film police officer to "the one responsible for solving crimes in the foodie industry."
