Однажды в Ростове

USSR, June 2, 1962. After the reduction of wages and price increases, residents of Novocherkassk went to a peaceful demonstration. But passions quickly heated up and led to a tragedy - the shooting of protesting workers, despite the protests of General Shaposhnikov. The authorities manage to hush up the tragedy, they take a non-disclosure agreement from witnesses, and all those who disagree receive prison sentences.
