Thomas Jerome Newton is a humanoid alien who has come to Earth on a mission. He hopes to save the remaining 300 aliens who are dying on his home planet. Since childhood he’s been preparing for this, training by watching and listening to Earth’s radio and TV broadcasts. Being mostly humanoid in appearance, and understanding much of Earth’s culture, he has disguised himself to successfully pass as a man from Kentucky.
Soon after his arrival, he contacts a patent lawyer and begins to “invent” the technology of his superior planet.
