Renegade adventurer Hunter (John Beck) and his daughter Nadia (Julie St. Claire) discover, in a remote Siberian cave, inventor Nikola Tesla's deadliest device: A machine that can turn human brain waves into explosions, big and small. While returning the doomsday device to civilization by means of passenger plane, a band of terrorists led by Beck (Hannes Jaenicke) gets on the plane with plans to move the machine to a second plane and blow up the first one in mid-air, with the ten other passengers as well. But Hunter thwarts the scheme at a grave cost: His plane crashes in the mountains of British Columbia. The CIA dispatches Jason Ross (Treat Williams) to find the device, rescue the survivors, and stop the terrorists. Meanwhile, the crash survivors struggle with freezing temperatures, an avalanche, and a man-eating bear.
