In the early to mid 1980s I recall that on BBC1 (I think) there would be a series of episodes from a kids drama, lasting about 6 or 7 episodes and possibly broadcast on a Friday afternoon. There's one particular series I was taken with because it seemed so eerie and "next level" (to me, the 9 or so year old watching it).
I recall something about a "Faculty" which was doing (scientifically?) questionable things and possibly a kid (or group of kids) investigating it and coming up against the Faculty's leader/security. I recall scenes of crows being scared off whenever a specific thing happened (repeatedly) at The Faculty.
That really is all I can remember. I posted this once before, years ago on a dedicated TV series message board but got no leads. Someone help me rest my mind!
EDIT: This Faculty (We've now discovered is actually "The Icarus Foundation") were performing, manufacturing or otherwise manipulating time or human behaviour.
