In winter of 1988, the Soviet Union demands aid from the West in the midst of economic ruin. Negotiations between NATO and the U.S.S.R break down, and in June 1989, the Soviet Union invades and captures West Berlin. Several months later in late November, 1989, a few months after the outbreak of World War III, Soviet forces launch a surprise invasion of Seattle, Washington. A combination of regular U.S. Army and National Guard soldiers, led by Lieutenant Parker and Captain Bannon, counter their advances to ensure the safe evacuation of civilians, before retreating due to the strength of the Soviet offensive. Joined by Colonel Sawyer, they continue to withdraw southwards, eventually leading a successful effort to retake the town of Pine Valley, halting further Soviet advances.
