Friday (Jack Webb) and Smith (Ben Alexander) receive a tip that the Plaza Royale, a fancy downtown hotel, is being used as a clearing house for "high grade" merchandise from an Eastern heroin ring. Going undercover, Friday poses as "Joe Edwards", a potential buyer from Phoenix. Though it appears that he has gained the confidence of the dope pushers, Joe discovers that his new "partners" plan to kill him at the first opportunity! Future TV producer Aaron Spelling appears as a squirrely junkie-informant. This episode is based on the Dragnet radio broadcast of May 31, 1951. ~ Hal Erickson, Rovi
