Chen An is the only feminine outlier in the three generations of the Chen family. He is out of place in the family with his humorous talk and handsome appearance. However, because he has the ancestral secrets, he is insidiously framed by his second uncle Chen Kun and foreign enemies. He is accused of colluding with the society to steal the family's core assets, and is eventually "exiled" to the Yau Ma Tei slums by the old man. In a desperate situation, he unexpectedly awakens the "imagination reality" golden finger - as long as the logic of his imagination is self-consistent, he can temporarily realize the skills, props and even scenes of the Hong Kong comprehensive world. Faced with the chaotic order of the slums, the turf wars among the associations, and the eradication of his second uncle, Chen An used humor to resolve the crisis and counterattacked with subtle means: relying on his imagination to demonstrate "police force negotiation skills" to persuade the young and Dangerous, using "undercover disguise" to infiltrate hostile forces, and using "business sophistry logic" to cut off Uncle Hu's business. In Yau Ma Tei, he made friends with the affectionate policemen and the hidden boss with special skills. While fighting Chen Kun and the Hong Kong TV drama villains behind him, he used his imagination and skills to accumulate strength. He counterattacked from a gangster in the slums to a being that Hong Kong's business community, police circles and associations dare not provoke. He finally exposed his second uncle's conspiracy, regained the family power, and lived a unique and unrestrained legend in the Hong Kong TV drama world.
