A long, unlikely time from now (1986), the scientist-engineers of Universal Transmitting Co. develop a way to send beings to far places on radio waves. One day a blonde disappears; a lady's umbrella arrives in Chicago without the lady; and why did she carry an umbrella on a hot day? Foul play, and aliens from outer space also kidnap UTC's head scientist... Inventive, and the aliens who play 4-D chess in which pieces are hallucinations are very likable non-monsters.
