Friday (Jack Webb) and Smith (Ben Alexander) are dispatched to a cheap hotel room, where young drug addict Mona Fenton has apparently attempted suicide. Acting upon the possibility that the girl was actually the victim of attempted murder, the two detectives conduct a citywide manhunt for Mona's supplier, identified only as "a guy with a flashy foreign car." And what about the unfortunate girl's hot-tempered boyfriend? This episode is based on the Dragnet radio broadcast of January 12, 1954. ~ Hal Erickson, Rovi
