DA Rudolph Cox (Leslie Nielsen) hopes to use the testimony of stoolie Lou Heinz (Bernard Kates) to put mobster Mac Davis (Harold J. Stone) away for keeps. Unfortunately, Heinz's cover is blown and he is marked for death. Even more unfortunately, the most important official in town seems to be in Davis' pocket -- which means that Cox's dreams of becoming a major political figure are in just as much danger as the hapless Heinz. This is the final episode of Alfred Hitchcock Presents' sixth season. ~ Hal Erickson, Rovi
