In the not-too-distant future a professor from a military great power wants revenge for his son (who was a paratrooper KIA during a war) and thus invents a weapon capable of ending the conflict – an automated mind-reading tank that detects and reacts to human feelings of hostility and fear.

After his revenge successfully takes place (as the tank destroys a number of generals responsible for the loss of his son) he himself falls victim to his own creation.

Polygon was directed by Anatoly Petrov (born 1937) and it was based on a screenplay by Sever Gansovsky (edited by Arcady Snessarev).

The animation then actively moves the virtual camera to change perspective dynamically for each scene and give a sense of realism, without the use of any CGI methods (which were not available at the time).

The characters in this animated film were designed with faces very similar to those of several famous movie actors and celebrities of the time, including Ringo Starr, Jean Gabin, Paul Newman, Yul Brynner and Mel Ferrer (The professor) among others.
