Four explorers are summoned to Peru by the brilliant physicist Dr Thorkel. They discover a rich source of radium and a half-mad Thorkel who shrinks them down to one-fifth their normal size when they threaten to stop his unorthodox experimentation.
A tense, claustrophobic journey into paranoia as a mad scientist's experiment goes horribly wrong. This vintage sci-fi adventure delivers thrilling, B-movie chills with a sense of creeping dread.
