Strange Invaders

Strange Invaders is a movie starring Paul Le Mat, Nancy Allen, and Diana Scarwid. Alien beings, whose settlement in a small midwestern town, are disturbed by a young professor determined to rescue his son from their clutches.
Charlie's ex-wife disappears, and he goes to where she grew up--a rural town in the midwest--to look for her. But, surprisingly, nobody knows about her or any of her many relatives, the Newmans. He meets aliens; but when he contacts the FBI, they don't believe him. He tells his story to a tabloid; and suddenly, he is chased by the aliens.
