Someone has been forging checks and spreading them throughout the city. Once all the evidence is in, Friday (Jack Webb) and Smith (Ben Alexander) can't believe that the "perp" is a sweet little old lady, Mary Walker (Myra Marsh). She insists that he intentions were honorable--but when has that sort of excuse ever held water with Sergeant Joe "By the Book" Friday? Based on a Dragnet radio episode first heard on October 19, 1950,this TV version features Dorothy Abbott, soon to be cast as Friday's ersthwhle girlfriend Ann Baker, in a bit role as a model. ~ Hal Erickson, Rovi
