Per its title, the plotline of this film is motivated by a counterfeit $50 bill. The funny money is passed to shopgirl Christa (Lucie Englisch), who, fearful of being arrested, hides it in a baby's piggy bank at her home. In dire need of money, Christa's sister "robs" the bank and puts the bill into circulation. Eventually, the faux banknote falls into the hands of Frau Lehmann (Kathe Haack), the mother of a banker (Theo Lindgren); the banker just happens to be in love with Christa. The plot alone is enough to induce chuckles, but the producers of Ein Falscher Fuffzinger felt the need to truckle to the lowest common denominator by throwing in a whole bunch of gratuitous slapstick. ~ Hal Erickson, Rovi
