The film is an intimate story about their families that had similar destiny in the World War II period. That made Petra and Brand tackle the project which took them to Slovenia, Macedonia and Cuba, where Brand’s father Carlos came from. “The point in all this is the twisted values of ethics in the past 20 years,” Ferro said, stressing a sentence of his Cuban grandmother quoting Castro: “A better world is possible.” The film starts with Brand and Petra and their idea to exchange genetic material and ends with their daughter Terra and a quote by a Cuban poet that children were born to be happy. They come to this point after they tell the tragic destinies - in Slovenia, through Petra’s grandfather and the Domobran movement, and in Macedonia, through Brand’s family story about his mother Ilinka Petrusevska and neighbor Milica Ruben and Kiro Gligorov, who remembers hiding Carlos in Skopje or the death of the most progressive member of the Petrusev family and fighter for independent Macedonia, uncle Brand Petrusev. The main character in Cuba is Carlos’ mother who lived to see her son 42 year later and her grandchildren Brand and Alisia and Pablo for the first time. “The Grandmothers of Revolution” received exceptional reviews for the topic and rich visual contents with usage of archive materials from Slovenian and Cuban archives and private family files.
