Director Marta Kovářová filmed a “global home essay”, which is a portrait of her father Jiří Svoboda, a renowned physicist who comes up with a “simple” plan to save the world – to unify the carbon mining fee system. But because Jiří is only a suspicious physicist and not a climatologist or a politician, his voice is not heard in the public sphere. Although the two tour international summits together, their efforts seem to have made no progress after a year and remain their private domestic revolution. While this fact exhausts Marta emotionally and she blames herself, Jiří maintains a phlegmatic approach, not only to issues of science but also to life.
