Hello, this is driving me demented as nobody seems to know what I'm talking about! I can remember rushing home from school at lunchtime when I lived in Glasgow circa 1975 to watch an animated science-fiction adventure story for boys on Scottish ITV. It seemed to be about a boy discovering some very sinister men getting up to no-good in a cave! I seem to remember one man was hooked up to a machine and he was electrocuted and you could see his whole skeletal features. The animation was pretty crude and as far as I know it's never been repeated but I would love to see it again. Any suggestions what it could be or did I just dream it ??
