Space invaders impregnate six women with super-powered offspring.

A UNESCO survey reveals six children, all the same age, in six countries who show identical and impossibly high scores in intelligence tests. The four boys and two girls, who come from Russia, the United States, Great Britain, India, China, and Africa, are brought to their respective embassies in London so that scientists may study their ability to communicate telepathically with each other, their power to impose their will on others, and other supernatural abilities. Their mothers, who are unable to explain the phenomenon, all insist that the children had no fathers. The children, led by the English boy, Paul, escape and hide in an abandoned church, taking with them Susan Eliot, Paul's young aunt. With their powers they turn away fearful government officials who have decided that the children must be destroyed. A scientist, Dr. Tom Lewellin, shocked by the government's plan to kill the six, persuades the chief of the UNESCO project to talk to the children. The children demonstrate their own higher morality but not in enough time to save themselves. An attack is accidentally launched, and the church and the children are destroyed.
