The Blue lake, or Tso Ngombo as tibetan call it, or Koko Nor for the Mongolians, is the largest lake in China at an altitude of 3200 metres. It is situated in the north west on the tibetan Highland. On the western shore stands the new monastery of Garla Gampa built on the ruin of an ancient monastery destroyed during the cultural revolution. Over a 100 monks, mostly young boys, live there and study the secrets text of Tibetan Buddhism with their teacher Geshe. The young nomads come from nomad families who raise yaks and sheep on the mountain slopes around the lake. The terrible Koko nor bandits of the past have become peaceful and hospitabl cattle breeders. Their life and the life of the monastery are the subject of this film.
