Plot synopsis: Such changes took place in Poland over a period of several months - from the end of 1988 to the end of January 1990? Michał Bielawski, through the prism of official and underground archives, shows the then state of mind of Poles, their fears, hopes and reflections. Film materials from the 1988-1990 period are in harmony with the photographs and diaries written by Poles at that time, as well as with the messages about the changes taking place. We observe the most important political, social and moral events of that period, confronted or reinforced by the comments of their active observers: ordinary people, politicians of the government camp and oppositionists.
