The Final Countdown (Ending Scene) | Village Of The Damned

Just when the horde think they have the humans where they want them, Christopher Reeve's, Dr. Alan Chaffee builds an impenetrable mind wall before hitting the self destruct button and blowing up the barn!

From Village of The Damned (1995): Ten months after the small California town of Midwich was struck by a mysterious event during which everyone in the village fell unconscious at once, 10 local women give birth on the same day. As the unsettlingly calm and unemotional children grow at an abnormally fast rate, it becomes clear that they can read adults' minds and force people to harm themselves. Local doctor Alan Chaffee (Christopher Reeve) and federal agent Susan Verner (Kirstie Alley) must team up to battle the alien children.
