The wife of Commissioner David Ho (Philip Chan) of the Inland Revenue Department (IRD) is suspicious that her husband is cheating on her.

Ho sends junior assessor Yau Ho-kei (Leon Lai) to investigate Hui's income.

At this time, the IRD is investigating businessman Hung Sam (Sunny Fang) for tax evasion, but the case is progressing slowly.

But after discovering that Hui is a fortune teller, he hires the two, greatly trusts them, and reveals to them his drug business.

Andrew Saroch of Far East Films rated the film 4 out of 5 stars and wrote "The Magic Touch features a constantly watchable narrative and a number of hilarious scenes; foremost among these is Hui's attempts to feel the villain's knuckles in a number of different and highly amusing situations.
