A security agent investigates sabotage and murder at a secret underground laboratory, home of two experimental robots.
Above-average, original sci-fi drama within a Cold War background still is quite silly, but quite entertaining and it's good color cinematography is enjoyable to watch.
Halliwell*: "Brisk, imaginative low-budget sci-fi in gleaming colour, well staged and developed."
Maltin**: "OK sci-fi..."
