Hey all, this is really random but I'm dying to find a movie I saw as a kid. I don't have many facts, but basically there is an arbitrary line crossing a town, in that if someone crosses it they die/pass out.
There is a certain scene where a few policeman are lined up on the border and one is walking slowly towards the line and he crosses it and passes out. I believe it may have been in black and white.
The internet amazes me sometimes, but google hasn't turned up anything due to non-specfic search words.
