Shen Zhile, a small official in the capital, has a life creed of "eating and waiting to die", but by accident, he is bound to three "unreliable" friends: Qian Manguan, the boss of the dental shop who is obsessed with money but stingy, Wu Sansi, the young boss of the escort agency who is not good at martial arts but loves to get into trouble, and Wen Ruyu, a failed scholar with a sour but poisonous tongue. The four of them wanted to live a peaceful life quietly, but they were involved in a series of ridiculous incidents such as the "Pearl Hunting Case in the Capital", "The Mystery of Water Transport Smuggling" and "The Secret of the Imperial Tomb". Relying on the luck of "a blind cat catches a mouse" and the tacit understanding of trying to undermine each other but never abandoning each other, they made jokes and solved strange cases on the crazy investigation road. In the end, they counterattacked from "the four unreliable people in the capital" to the "four lucky stars among the people". The whole process is full of laughter but still warm, full of fireworks, full of sense of immersion, and the ending is successful, without any regrets.
