1980's movie
New here but thought I'd post to see if anyone can help with a movie title.
1980's movie where there's an alien craft that was found past a hill ( the visual is literally a hill with like a fence) and kids find their parents acting weird, like too nice to be mom and dad. It turns out that their parents are actually aliens kidnapping adults and taking them to the ship. A group or a couple of kids plan to rescue their parents and go to this creepy ship over the hill.
That's about all the info I've got. It was kind of a B movie like, similar to The Gate or Terror Vision. If anyone know, I'd appreciate the feedback, thanks.
