An HSV-7 news crew covering a story on pollution discover two bodies near the Maribyrnong River. The Homicide squad not only have to find the killer, but also establish the identity of the people killed. Forensic tests come to nothing, but an appeal to the public results in a positive identification - a husband and wife thought to have been on holidays. Their killer is the husband's father, and his motive has strange religious overtones. Notes: Scriptwriter John Drew had a middle and an end to this story, but did not quite know how to start it, as it called for the discovery of two bodies in an area where no-one would normally go. The solution was to use a news team doing a story on pollution. Newsreader Brian Naylor appears as himself.
