Mittags auf dem Roten Platz.

In August 1968, troops from the Warsaw Pact countries occupied Czechoslovakia, bringing an end to Prime Minister Dubcek's reform policies. Many people in the West protested against the crushing of the attempt to create "socialism with a human face." However, the world public paid little attention to the fact that at the same time, a handful of Russians were demonstrating in Moscow against the actions of their own government. The film reconstructs the trial of the Russian "dissidents."
