Um... decades away? This was 1974. There had been plenty of movies, books, radio dramas and tv shows dealing with UFOs and aliens since way before 1974.

When a respectable couple believes they have seen a flying saucer, they agree to keep it quiet, though when she speaks with her neighbour wife, she learns that they saw it too. While she doesn’t let on, she talks more to her husband about it. He is adamant that nothing happened and goes about his business. A short time later she is befriended by an alien who enlists her cooperation eventually implanting a mind-control chip in her…What can save her, and the human race from certain obliteration? You have to love the voice of the alien.
