The Rwenzori range on the Uganda-Congo border rises into a landscape climbers describe as alien: giant lobelias, huge fern trees, and bamboo forests shaped by extreme altitude and near-constant fog. Leopards, elephants, giraffes, and red forest antelope move through the terrain below a canopy full of monkeys and birds. The film follows brothers Makumbi and Musa, young men from a village at the foot of the mountains, as they take on their first solo job as guides, leading a group of foreign trekkers up the slopes without their trainers alongside them. Their trek becomes a window into how local families make a living from an increasingly fragile ecosystem, and into the skills passed down for reading weather, terrain, and altitude sickness on a mountain that punishes mistakes. Real footage from the climb, interviews with the guides and their families, and shots of the range's strange high-altitude plant life carry the film, which treats the Rwenzori as both a natural wonder and a disappearing way of life for the people who work it.
