A millionaire has plans for an army of robots to do the perilous jobs of human workers. In his lab he has a scientist tackling the problem. But like so many sci-fi movie scientists, he goes bonkers and creates a giant, unstoppable robot for his own evil plans. The climax with Schmitz, Schurenberg, and Franck in the massive electrical chamber is awesome. Franck turns in a wonderful performance as the mad Professor Wolf.
