Gustav Klucis (1895-1938) is Latvia's most famous artist, although he never worked in Latvia. Klucis was an avowed communist and one of the most distinguished members of the Soviet avant-garde. He is famous to this day mostly for his constructivist photomontages: Agit-Prop work that artfully expressed the victory of communism. Nevertheless, Klucis fell victim to Stalin's terror in1938. He was arrested as a counter-revolutionary and later executed. His son Edward was two years old at the time, the same age as director Peteris Krilovs, whose father fell victim to Stalin in 1951. Krilovs combines extensive documentary film material with staged scenes, also using letters by Klucis' widow alongside his own research to retrace Klucis' tragic end. Furthermore, the film evokes an atmosphere of the revolutionary avant-garde by reconstructing and analyzing Klucis' photomontages with modern, dynamic animations.
