What happens

The episode is part of the Ranger Bill series.
A mountain road on the way to Central City, and then a strange valley below the highway.

Listen for: The sudden crash and the sounds coming from the valley.
Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
