Byttinger
Byttinger is a 1991 Norwegian drama film directed by Sigve Endresen, starring Bjarte Hjelmeland and Stig Henrik Hoff. A group of seven inner-city youths are given the choice between prison and a rehabilitation camp in the countryside. The two social workers who follow them there believe that the fresh air and beautiful scenery will have a positive influence on the kids. During an excursion to a glacier the group gets trapped, and the kids have to use all their street smarts to get out.
