Urmas Eero Liiv's feature film "Must alpinist" (Ghost Mountaineer) is a youth film with elements of horror which is based on real life events which took place during the Soviet era. It tells the story of an Soviet Estonian student hiking group which gets caught up in a series of scary events unfolding in wintry Siberia. The unpopular group leader Olle (Reimo Sagor), who becomes disappointed in his companions during the trip, disappears on the last day in the mountains. His rival, liberal-minded and adventurous Eero (Priit Pius) guides the descending hikers into a Buryate village on the mountain to seek help. A weird and insane chain of events is unleashed which seems to be orchestrated by the missing Olle. In a foreign land and among people they do not know, the hikers are faced with a task which they at first do not want to undertake and later are unable to tackle.
