Watch Subzero (2005) Official Trailer

Hell has never been so cold

A device that controls a powerful Russian-made satellite weapon is stolen by Russian terrorists, who try to escape by flying out but are shot down. The device is now on top of K2. The device is still active and where it will strike is indeterminable. The good guys have to get to the device and deactivate it. Only trouble, it's winter and it'll be difficult to climb K2. A few of the best mountain climbers in the world are recruited to take techs who can deactivate the device to the top of K2. However, before the climbing party leaves, a team member dies, and it might not be natural causes. The group who stole the device might have someone on the team. But they still go on.
