The Battle of Shanghai has been described as the last battle of World War I, and the first battle of World War II. It was a warning to the world, a warning that was ignored. And it was the place where the destiny of modern China was set in motion. Based on the book “Shanghai 1937: Stalingrad on the Yangtze” by Danish author Peter Harmsen, this film introduces key figures in the conflict, chronicles how the battle unfolded over the course of three months, and explores the aftermath and years of war that followed.
