Through the conversation with Yugoslav film authors and excerpts from their films, this documentary film tells a story of a film phenomenon and censorship, and its focus is, in fact, a painful epoch of Yugoslav film called "a Black Wave", which was the most important and artistically strongest period of Yugoslav film industry, created in the sixties and buried in the early seventies by ideological and political decisions. The film tells a great "thriller" story of the ideological madness that characterised the totalitarian psychology and has left multiple consequences, still felt up to this very day. It stresses similarities between totalitarian regimes defending their taboos on the example of the persecution of the most important Yugoslav film authors. Those film authors have, however, made world careers and inspired many later authors. The film is the beginning of a debt pay-off to the most significant Yugoslav film authors.
