of the Guard company. Caffey goes out on a search mission and discovers one of the Alaskan Scouts still alive and learns of the Soviet incursion. Caffey then shadows the Soviet troops after notifying the Fort Wainwright commander, General Roberts. The general flies to the scene only to be seen by the Soviets. Caffey takes command of the Guardsmen when his senior officer General Roberts, who did not believe the news of the invading Soviet troops, is killed in Caffey's first firefight with the Soviets. Caffey notifies the Pentagon by radio of the situation. Upon learning of the situation, US President Thomas McKenna (Rock Hudson) orders Caffey's National Guard troops to be federalized and orders Caffey to do all that he can to stop the Soviet troops. McKenna orders a media blackout on the emergency but then orders US forces to be mobilized in response to the Soviet incursion under the pretext of unscheduled training exercises. McKenna fears that the US people will demand a declaration of war against the Russians for the attack. Fierce winter weather prevents US military units from bases and forts in southern Alaska from reinforcing Caffey's unit. Caffey deduces the Soviet assault unit's goal. He uses the two US Army helicopters at his disposal to move his unit to a new pumping station ahead of the Soviets. Meanwhile, Soviet Premier Gorny (Brian Keith) has learned that the Soviet military and KGB leadership have executed the plan without his permission. He is informed of the US mobilization and orders Soviet forces to a similar posture. In Alaska, Colonel Caffey realizes that his men have an inadequate supply of ammunition, grenades, and mines. Using combat tactics that he learned in Vietnam, Caffey sets up a defensive perimeter around the pumping station making use of surplus lengths of large-bore oil pipe to establish a position from which to ambush the enemy. The Soviet troops approach the pumping station, unaware of the American soldiers' presence until they trigger US land mines buried in the snow. The Soviets suffer casualties and fall back, but they continue to surround the buildings. McKenna and Gorny secretly meet in Iceland to negotiate an end to the crisis. They are unable to reach an agreement, and both return to their countries but promise each other that the talks will continue. The US responds to the Soviets' continuing mobilizations, as officials recognize that they are
