Weeping Rocks follows Art, an entomologist nearing the end of his life, who has spent over five decades walking the same ten trails, meticulously counting every butterfly he sees and witnessing the slow erosion of the world. His eccentric, patient research has uncovered patterns of decline that went unnoticed for years, revealing the deep environmental impact of detrimental human activities. As time reshapes the landscape and species fade, Art’s journey becomes a meditation on mortality, change, and the beauty of what remains.
