High in the Himalayas, an aging Bon lama faces an uncertain future. His spiritual role has passed from father to son for generations, but his own son has made a new life as a sushi chef in New York. Traveling between the dramatic landscapes of Mustang and Dolpo and the Himalayan community of Queens, filmmaker Kesang Tseten explores what happens when ancient traditions encounter migration, modernity, and a changing climate. Moving between spectacular landscapes and everyday family life, The Lama’s Son looks beyond romantic visions of a timeless Himalaya to ask a difficult question: what can be preserved when the future seems to lie elsewhere?
