Thanks so much for the suggestion! However, Brainwaves is sadly not the one I’m looking for.

Thanks for taking the time to comment! Interesting - I can't find that one, can you help me out?

I think this is a movie, rather than a series/miniseries. I think it's from the early 90s or late 80s (but it could be older). I think it's either an English- or French-language production. I think...

Just a guess, maybe "The Crooked Web" (1955)? https://www.imdb.com/title/tt0047962/
