Amongst the hustle and bustle of Kuala Lumpur city lies an isolated forest, home to one of our closest living relatives. Gibbons live in small family groups and mated pairs sing duets every morning in a coordinated fashion, but this isolated forest only has one song. Finding Solo follows Malaysian filmmaker, Myles Storey, as he returns home in search of Solo, a white-handed gibbon believed to be the last of his kind in this patch of forest. With help from a primate photographer, local hikers, and Malaysia’s leading gibbon expert, Myles tracks down Solo, discovers how unique gibbons are and witnesses the direct impact that human development can have on their lives. This is Solo’s story, but what will he teach us about ourselves?
