“not human life form”
I saw this in the early 80´s on TV in colour. It was the kind of movie of “people been replaced with duplicates”. Cant remember if they were demons or aliens or else. But i remenber then scene when the suit sensor confirms his supicions. And the he goes and rescue his family. The suit had weapons.
Sorry for errors, my english is really rusty. Thanks
