Ancient Egypt, one of the oldest civilizations in the world, was a total mystery to historians. For 1400 years, the ability to understand hieroglyphs had been lost to the world.

But in a chain of events that involved Alexander the Great and Napoleon Bonaparte, a stone was discovered that would prove to be the key to Egypt's ancient secrets. And two bitter rivals set off on a race to turn the key first.
