The Redhead from Alpha Centauri

In the twenty-second century, a redhead from the Alpha Centauri star system, lands in the Death Valley. She convinces reputed American astronomers that she is a peace-seeking E.T., but members of the Planet Preservation Society destroy her spaceship and send an assassin to kill her. The assassin, who happens to be the son of a French-Canadian billionaire, falls in love with the E.T., and helps her escape across Europe and Asia. But he must return to his father's bedside, and relinquish the E.T. to the American astronomer, who is her true love. The couple escapes to Japan, and finally finds peace and shelter in India.
