At a press conference, Engineer Vajshoblhák presents his groundbreaking invention - a dictarobot. The machine - similar to a typewriter - is able not only to reproduce a dictated text directly into written form, but also translate it into several languages. The curious questions of journalists, however, are met only with the inventor's vague and foggy answers. The nation of Cangaras has already ordered one million of the machines and the state's worldly business representative wishes to meet the inventor. Both Vajshoblhák and his colleague Konipas, acting as interpreter, are fascinated by the stranger and his petty gifts. The engineer explains in detail the principle of his invention. But before the Price Control Commission manages to calculate the price of the machine, Cangaras cancels its order - having his own, cheaper machine already. Konipas and Vajshoblhák are fired. In their new work-place, they keep state secrets even when it is detrimental to do so. The film ends up by warning: "Keep state secrets when necessary".
The film was made to order for the Ministry of Interior of the Czechoslovak Socialist Republic.
