The story evolves around a radio panel game show "Twenty Questions." The panel is challenged with an anonymous question. The answer leads to a series of murders in which the killer uses the programme to name his victims in advance. Two reporters spot a link between them and enlist the aid of the panel in trapping the guilty party.
