Friday (Jack Webb) and Smith (Ben Alexander) go after an enterprising gang of auto thieves who double as con artists. Using the classified ads as their guide, the crooks "purchase" cars from their owners by using phony checks, then resell the vehicles for a profit. Based on the Dragnet radio broadcast of October 4, 1951, this episode features another scenery-chewing opportunity by frequent series guest star Virginia Gregg. ~ Hal Erickson, Rovi
