I wish I knew where, been searching for it for years now.

I can give you what info I got. It's a canadian movie. In Canada its title was "Antidote". I had the luck to watch it twice on Tv, but since then it never was repeated.
One or two years ago I found it on VHS on Ebay I think. But I didn't buy it then >_<

I wish you luck
