牧民多杰和旦巴两家因为连续的大雪,撤离雪灾而迁徙。他们赶着牛群去往夏季牧场,途中因山路崎岖加上大雪纷飞而迷了路 。在面临野狼袭击,丢失牛群,食物短缺,高寒刺骨的境遇中,为了活命,两家必须尽快赶路,摆脱险境……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.
