A noted scientist (Rex Reason) receives a mysterious package. Using every ounce of his intelligence, he constructs a mysterious machine contained in the package. Turns out this interplanetary communication device is a "test" sent by the faraway residents of the planet Metaluna. Now our brainy hero and a group of other similarly recruited scientists must travel to this alien world to help stop an all-out attack by inhuman invaders. This sci-fi classic from 1955 features some incredible images of outer space and one of the all-time greatest bug-eyed monsters--the Metaluna mutant!
