By far the best looking P.R.O.B.E. case file, this is some very nice atmospheric work. Unfortunately, it doesn't have a plot. There's a bit about an alien crashing and some London Underground stuff....

Location filming yay!!! Baggs' awful acting booo!!!

On location filming, and half decent editing and effects (the effects seem to be clips from something else, but still used to good effect here)

Story is meh though and because it's recorded on the underground some of the audio isn't the best

3/10
