The film reveals the mechanisms of the communist institution of censorship. Famous filmmakers - Kazimierz Kutz, Andrzej Wajda, Krzysztof Kieslowski, Filip Bajon and Marcel Lozinski - talk about their contacts and experiences with censors, how their films were censored, what parts were considered contrary to the ideology of the socialist state. These interferences were often of an absurd nature. At the same time, the filmmakers mention how much of the intended content they managed to smuggle out. The film is also an attempt to analyze and summarize the role of censorship in a totalitarian state and its impact on culture and art.
