Friday (Jack Webb) and Smith (Ben Alexander) search for the man who has robbed two stores. In both cases, the man handed a sealed envelope to the victim, with instructions to "hand over the money, or else." As it turns out, the person bearing the note had been strongarmed into doing the dirty work for the real thief--who remains at large. Versatile voiceover artist Paul Frees makes a rare on-camera appearance in this episode, which was based on the Dragnet radio broadcast of June 14, 1955. ~ Hal Erickson, Rovi
