The Invisible Barrier Keeping Two Worlds Apart

Synopsis

An ancient maritime boundary exists between the islands of Indonesia, specifically between Bali and Lombok, known as the Wallace Line. This line, established by naturalist Alfred Russel Wallace in the 19th century, marks a significant biogeographical divide, influencing the distribution of species across the region. The documentary explores the ecological and cultural implications of this boundary, highlighting how it shapes the biodiversity and human interactions in one of the world's most diverse marine environments.
