For most Christmas is a time for peace and goodwill to all men, but not for the pilots who protect us. When the Russians put at 'bear' in the air and it strays across the Russian - US border into US airspace they send Mike Fletcher and his wingman, Eddy, 'Dir Hard' Cortez out to shoo him back across the border. Loaded for bear with guided missiles and lethal guns they chase the elusive intruder through the dark winter sky's over the story sea of Alaska, ever mindful that the wrong move could start a war.
