In detailing the discoveries of a madman scientist wherein he is able to reduce the size of men and animals to miniature pygmies, story and direction both fail to catch and hold interest. Achieved through continual use of process and trick photography, idea gets lost in a jumble and pancakes off for a dull effort.
Albert Dekker, researching in the jungles of South America, finds a rich radium deposit from which he can draw concentrated energy for experimental use. He has already used the power to reduce animals to minute size, when a pair of mining engineers (Thomas Coley and Victor Kilian) and two biologists (Janice Logan and Charles Halton) arrive and soon discover his secret. Dekker gets the quartet, together with native Frank Yaconelli, into the radium machine room and reduces the group down to beings of a foot tall. From there on, it’s an unexciting adventure to escape the madman.
