Violent, bloody riots formented by foreign agents are breaking out in South Korea. Seizing the opportunity, North Korea launches a lightning invasion with heavy Soviet support, whose aim is to unite both North and South under Communist rule. The Second Korean War has just begun - and World War III may not be far behind.

This climactic conflict is soon engaged on all fronts - land, sea and air. Soldiers fight in Korea's snow-covered hills and frozen paddy fields ... F-16s race into dog-fights over the 38th Parallel ... Ultramodern submarines glide into battle in the eerie silence of the deep Pacific. And from the hushed, anxious corridors of power in Washington, Moscow and Beijing the growing war spreads its explosive ripples towards Europe, Japan and the world at large.
