The Hidden Ships of the Gold Rush drains the streets of San Francisco, the Sacramento River and the icy wastes of the Klondike, northern Canada, to tell the true story of nineteenth-century gold mania. In the race to be first to the gold fields hundreds of thousands of people from across the world head West. Risks are run, countless men, women and children die, fortunes are made and lost - and amid it all, the modern-day United States is born.

For over fifty years the world's two greatest superpowers, the United States and Soviet Union, pour their resources into a terrifying array of doomsday weapons and military machines. The Cold War is the world's first nuclear armed confrontation. Remarkably, it's also the greatest clandestine war in the history of mankind - conducted in secret beneath the waves. Now, with access to daring expeditions, precision data and classified information, we use ground-breaking computer-generated-images to drain the ocean and reveal the shocking secrets of the nuclear-armed Cold War.
