An energized documentary filmmaker (Krystyna Janda) fights 1970s government censorship as she seeks the buried truth about bricklayer Matuesz Birkut (Jerzy Radziwiłowicz), a state-manufactured “people’s hero” during the Soviet-controlled 1950s. Directed by Andrzej Wajda, this film-within-a-film blends documentary and fictional techniques and serves as a reflection on national history and mythology.
