High in the Tibetan Himalayas, two families of yak herders battle against the elements to bring the herd home safely. When a blinding snowstorm sends them off course, they face a series of impossible decisions if they are to survive. The stunning locations are accentuated by stark black and white photography that imbues Lost with a timeless quality. Produced by Pema Tseden, Lotan's film excels as both a breathless survival thriller and heart breaking eulogy to a disappearing way of life.
