In the dark opening days of the Second World War, Japan marches unhindered through China and Southeast Asia. They decimate the American Fleet at Pearl Harbor. Grind the Philippines and the remaining American territories in the South Pacific beneath their bootheels. Not even the North American continent is immune as the Japanese conquer Alaskan Islands.

Four young Americans, three men and a woman, travel to China to assist the embattled Chinese. The woman works in her father’s mission hospital bombed relentlessly by the Japanese, while the men join the American Volunteer group. These men, flying in support of the Chinese, become the only threat to the brutal conqueror’s ambitions. For a shining moment, this band of young people, who become known as the Flying Tigers, stands alone, thwarting the death that rains down on Rangoon.

While struggling against these impossible odds, personal challenges threaten to tear these young people’s lives apart. Can they prevail where others have failed?

While Americans cheer their efforts, Winston Churchill compares them to the brave airmen who defended the United Kingdom during the Battle of Britain. Of those, he said: "Never in the field of human conflict have so many owed so much to so few!"
