Four scientists - mining engineers Bill Stockton (Coley) and Steve Baker (Kilian) and biologists Mary Mitchell (Logan) and Dr. Bullfinch (Halton) - are summoned by Dr Alexander Thorkel (Dekker) to his laboratory in the Peruvian jungle. But when they arrive they find Thorkel has brought them all the way there only to identify crystals under his microscope, because his own eyesight is too poor for him to see them himself. Insulted, they set up camp in Thorkel’s stockade until he will tell them more about the experiments he is engaged in. When he finds them snooping in his laboratory, he angrily locks them inside his atomic generator. And when they emerge they find they have been shrunken to twelve inches tall. At first willing to play-act the role of benevolent despot with his miniaturized captives, Thorkel reveals the more sinister side of his personality by abruptly murdering Bullfinch in cold blood (easily the film's most frightening sequence). The rest of the picture details the escape efforts of the three pint-sized protagonists as they hack their way through a jungle of gigantic foliage and do battle with oversized wildlife.
