Synopsis (Wikipedia):

"The film's plot is centered on an engineer Jim Ripple who invents universal robots to help workers, being himself from a workers' family. He theorizes that cheap production will make all goods so cheap that Capitalism will fall. The workers do not share his view and his family considers him a traitor. A key element of his invention is a high-capacity capacitor that powers the robots. The government becomes interested in the invention because the robots can be used as a weapon as well. Ripple is given a top secret factory and funding so that he can produce robots. The robots are not autonomous or intelligent, and controlled either by radio or by sound, for which purpose Ripple uses a saxophone."
