Friday (Jack Webb) and Smith (Ben Alexander) go on the prowl for a holdup man who has hit several bars in a period of a few days. The felon's MO is identical in each case: he orders a scotch and water and turns on the same jukebox song before pulling out his gun. The detectives intensify their efforts when the elusive robber kills a bartender. This episode is based on the Dragnet radio broadcast of November 10, 1949. ~ Hal Erickson, Rovi
