Joe Friday (Jack Webb) and Frank Smith (Ben Alexander) are tipped off to a huge shipment of European heroin (three kilos, uncut), which is to be brought in to LA and peddled to teenagers. To catch the drug smugglers, Friday again goes undercover--but has he been set up as a "dead duck" by police informant Hugo Kenley (Richard Benedict)? It sure seems that way when one of the suspects instantly recognizes Joe as a cop! There's plenty of authentic drug jargon ("Manicured Mary", "tea party" etc.) in this episode, which is based on the Dragnet radio broadcast of March 1, 1955. ~ Hal Erickson, Rovi
