Invisible Invaders

“A sci-fi shocker that'll keep you awake at night!”

A voice reaches the scientist Adam Penner (Philip Tonge) from beyond the grave, telling him that aliens have lived unseen on the moon for twenty thousand years. They give the nations of Earth one demand, surrender at once. Edward L. Cahn shuts Penner, his daughter Phyllis (Jean Byron) and Maj. Bruce Jay (John Agar) inside a sealed laboratory, where the end of the world gets argued in cramped rooms by a handful of people, with the invaders waiting outside.
