Sub-Zero

A stolen device that controls a powerful Russian satellite weapon ends up on top of K2 after the terrorists are shot down. The device is still active, and its target is unknown. A team of elite mountain climbers is recruited to take technicians to the summit to deactivate it. Facing winter conditions, the team prepares for the climb, but a member's suspicious death raises concerns of a possible traitor within the group. Despite the danger, they proceed with their mission.
