Synopsis:
Jul Van, a peace-loving alien from Pluto, arrives on Earth ahead of a Plutonian invasion force to construct a machine that will repel the invaders. The machine, which can only be triggered by a particular sound that Jul Van refuses to disclose, passes its preliminary tests. Then, Jul Van is found dead, leaving the Earthmen to frantically try to identify the key-sound that will activate the machine. With time running out, scientist Ralph Baxter puts a desperate plan into action.
