The apparent 1958 suicide of a popular rock-and-roll DJ is reinvestigated after a documentary filmmaker discovers a tape recording made at the time of the victim's death by gunshot at his radio station. The probe reveals the victim had enemies, from angry parents who didn't approve of the music he played to record-company hucksters trying to bribe him to play records. Also, Valens tries to get his brother to testify against a suspected pedophile.

The 1975 disappearance of an 8-year-old girl who was never found is reinvestigated after a note written by the girl shortly before she vanished turns up. The probe reveals the white victim was best friends with a black girl who had recently moved into the neighborhood. Their friendship rattled many in the predominantly white neighborhood and the girls quickly became targets of hatred.
