Nocna zmiana is a 1995 Polish documentary film about the events of the night 4 June 1992 when the collusion of all polish parliamentary forces has removed Olszewski's cabinet out of ruling the country. It was directed by Michał Balcerzak.

The documentary chronicles the events that led to the removal of the right-wing, anti-communist government in post-communist Poland. The documentary revolves around the recording of the meeting of Donald Tusk, Lech Walesa, and Waldemar Pawlak that had the goal of removing the Olszewski's government before it passed a law allowing the public to see top secret government archives, listing communist collaborators. The main issue and worry was that the public would learn about Lech Walesa criminal past as paid informers of the communist government. The efforts were successful and the law never passed -- instead, Olszewski's government was removed from power. The public learned about Lech Walesa's collaboration as a paid informant only 20 years later, when the widow of the communist Minister of Internal Affair, Kiszczak, a person responsible for at least 200 murders, tried to sell the documents showing Walesa's collaboration and was detained for illegal possession of top secret archives.
