A teenage girl named Edna (played by a young Carolyn Jones) tells Sgt. Friday (Jack Webb) that her best friend Kathryn (Allene Roberts) is hooked on heroin. Kathryn's father (Malcolm Atterbury) is outraged by this accusation, insisting that the hypodermic marks on the girl's arms were administed by the family doctor to cure her allergies. Inevitably, however, the painful truth is revealed. Featured as one of Kathryn's "suppliers" is a pre-Adam 12 Martin Milner. This episode is based on the Dragnet radio broadcast of April 13, 1954. ~ Hal Erickson, Rovi
