Series 18 Episode 2 “The Incident at Cooper Hill”
Originally broadcast 13 January 2016
Mysterious lights are seen in the sky over famous UFO hot-spot Cooper Hill. When a local forest-ranger suffers a strange death, the visiting UFO spotters are convinced aliens are responsible. DCI Barnaby and DS Nelson unearth suspicions, betrayals and long-buried secrets in their search for the truth.
Here is their attempt at Science Fiction/Horror with Military involvement. It starts off interestingly, people get drowned in slime with a hint of conspiracy. Unfortunately it all ends in the usual sex and love triangle. There was potential here to inject some REAL science fiction, but the writers took the easy way out.
