In the radio broadcast service for the Missing Persons Bureau, a strange radio signal cuts in over the normally secure channel. Who could be doing such a thing? Where is the signal coming from? Can it be a message from the moon? Names are mentioned that match up with missing person reports, but nobody believes the report that Henry is giving. Mr Philo, a newspaper reporter is willing to listen to the theories that Henry, and the broadcast technician have been working on.
The plot thickens when a lits of names is found on Henrys desk, then they are the next ones for him to report as missing over his broadcast. As the facts emerge, and the newspaper reports hit the press, the synacal, grumpy boss begins to soften and listens to Henry’s theories. The broadcast studios seem eery and spooky after hours when the boss joins Henry in a meeting with the reporter as another moon broadcast is expected. Is there a conspiracey of some sort? Renegade scientists, slave labor, atomic energy, flying disks, invasions? What kind of danger has Henry exposed?
The boss is now a convert, and as he tries to keep Henry safe, and make a quick get away, things begin to fall apart. What kind of evil forces has henry gotten riled up, and on his case? What does it mean when he suddenly finds himself on a rocket that is blasting off for the moon? By the time he learns the truth behind the missing persons, and the evil plot to invade the earth, it may be too late for poor Henry. Good always triumhs over evil, right?
