High Citadel

Isolated in the biting cold of the Andes, after their plane has been hijacked and forced to crash-land, Tim O'Hara's passengers are fighting for their lives. While one group of survivors, lead by O'Hara, attempt to cross the peaks along a deadly, snow-covered pass, the other is working to stall the armed group of soldiers who plan to kill them all once they have managed to cross a torrential river. Ingenious ideas are put into action in a dramatic attempt to prolong their survival until help arrives.
