This movie is a portrait of an ecosystem, which gives us the only clue we need in the name: monism is the doctrine according to which all things that exist are part of a whole. That unifying point may be God, but here it’s a volcano. We are on the fiery Mount Merapi. Close to recent eruptions, a story is being rehearsed that unites different cinematographic registers and a community that has the volcano as its link. A film that may be emotionally challenging.
