Indonesia, today: a pair of scientists studies the activity of Mount Merapi; an intrepid female documentary-maker investigates the socio-economic realities of extracting volcanic sand, accompanied by an exploited and disabused miner who reveals the industry’s underbelly; a group of paramilitaries exerts a reign of terror over the region. This colourful community with its very different aims and interests populates a vivid fresco that explores, through a series of shifts in tone, the logic at work around the volcano. Riar Rizaldi jubilantly combines multiple cinematic registers, as if each dynamic had its own aesthetic. He uses both the bloody excess of the horror film and the informative precision of the documentary to offer us an explosive, unpredictable movie that mirrors its main character, this stratovolcano whose next eruption, according to scientific legend, could lead to the extinction of humankind as nature’s punishment for human hubris. For Rizaldi, the idea of supernatural forces is far more than an impressive tool to stage and twist the realities it models. Fantastic, incandescent figures haunt this landscape of extractions (extracting sand, data and information) better to challenge the prevalence of instrumental rationality. They accompany Monisme towards a visual and audio epiphany that suggests, in contrast to science set in its own dogmas, that, through the relationship it creates, belief in the spirits of nature is perhaps the most reasonable attitude towards the destruction of living things.
