This film, which took the top honor at the 1969 Berlin Film Festival, was directed by Zelimir Zilnik for the first time. It is a documentary that takes a decidedly anti-Stalinist view in the wake of the 1968 Russian invasion of Czechoslovakia and raises important political questions. The film states that although the world has experienced untold wars, there have only been a handful of revolutions with any lasting significance that lead to political change.
