Source plot synopsis — includes the ending
Test pilot Bruce Barton is missing and his girlfriend, Susan Winter, organizes a search party, which is sent out in the jungles of Mexico. Scientist Russ Bradford, mining expert Martin "Marty" Melville, and pilot Lee Brand fly into unknown territory. While searching the area, however, they uncover giant mutated Earth animals such as a mouse, an eagle, a spider, a green iguana, a lizard and a boa constrictor.
More importantly, the group encounter Barton, now a mutated 25-ft tall, one-eyed cyclops who became disfigured due to an exposure to radioactivity from massive uranium deposits in the area. This is responsible for the unusual size of all the other giant inhabitants of the region. Barton kills Melville, but appears to recognize Susan. When the cyclops tries to prevent the rest of the group from flying to safety, he is wounded in the eye by Bradford and dies.
