Acrobatic troupe magician Lu Xin is witty and funny, and his performances often win applause from the audience. He admired the Belgian detective Poirot and called himself Poirot II. Recently, he has been fascinated by detective films, and his mind is full of crime-solving plots that affect his daily life. In the mysterious Cuifeng Mountain case, he wanted to show his ability to solve the case, but he was frustrated. But he didn't give up, and in the pharmacy, he found two pickpockets stealing the girl's purse, Wang Jiajia. With his magic talent, Lu Xin deceived the wallet from the pickpocket, and skillfully returned the wallet to Jiajia with a little magic, winning the girl's favor. He also got acquainted with pickpockets, monkeys and Erwei. Soon, Er Wei had a love fight with another gangster leader, Birch Bark, and Lu Xin went to Birch Bark as a small leader to settle accounts. He used the trick of 'golden locks piercing the cheeks' to suppress the birch bark. Lu Xin and Jiajia embarked on the road of love, but Lu Xin, who was eager to solve the case, often missed the appointment, and Jiajia was greatly annoyed. In solving the case, Lu Xin discovered that there was a character named Lao K who was manipulating the gangsters. He once wanted to instruct someone to kill Lu Xin. After knowing the relationship between Lu Xin and Jiajia, he couldn't do anything, so he had to have a showdown with Lu Xin. Lu Xin was very surprised to know that Jiajia's brother Wang Hu was Lao K, and he tried to persuade Wang Hu, but Wang Hu turned a deaf ear. In the restaurant of the sea park, Lu Xin generously had a dinner with a group of hooligans, and when he was drunk, Lu Xin showed his true colors, and the pickpockets suddenly made a mess. Suddenly, Wang Hu rushed to the sea park with his thugs, but it was too late and he was captured by all the public security officers who had been prepared for a long time. Lu Xin was also taken into the prisoner car. Jiajia received Lu Xin's appointment to come to the paradise and shed tears when she saw this scene. Not long after, Lu Xin took the stage again to perform his best show.
