In repressive mid-1970s Poland, documentary filmmaker Agnieszka (Krystyna Janda) begins work on a film about Mateusz Birkut (Jerzy Radziwilowicz), a bricklayer who had briefly been hailed as a hero of the proletariat in the 1950s, but then disappeared into obscurity. In piecing together details about the bricklayer's mysterious life, she discovers that his involvement in organized labor had been viewed negatively by party bosses, and that her own investigations could put her in danger.
