Talented skiers from different schools are invited to a special ski workshop, to which only ten of them would have been invited. On the day of the seminar, however, eleven youngsters are standing at the ski hut, all with an invitation. A huge avalanche takes place and the hut is cut off from the outside world. However, supplies in the hut are limited and the three instructors advise the youngsters to work together or ask one of them to leave at random. As time goes by, the students begin to realize that their 'teachers' are not who they seem.
