A long serving communications executive feels certain he will be appointed president of the company. When he is passed over for a younger, more in-tune employee, he is extremely disappointed. Going on a drive with his secretary, the two muse about their lives, devoted to the company and to each other, and he is very bitter about his lot. Stopping at a garage sale, he finds a crystal radio set that is designed from his own prize winning plans he created for a contest as a youth. Purchasing the item he finds it still works, and he alone hears broadcasts from the distant past, and voices that, in communication with each other, spell calamity and disaster for the entire planet.
