The Irrawaddy River (also known as the Ayeyawady River) in Myanmar in the only place in the world where humans and dolphins fish side by side. Today, this unique tradition is in danger. Myanmar's economy has undergone rapid growth, and the river has become polluted, sending the dolphin population and their food sources into decline. Only 20 fishermen with the knowledge of this traditional fishing method remain. We follow seasoned fisherman Maung Lay as he works alongside the dolphins, and learn about the initiatives looking to preserve them.
