A new dam on the Nile could trigger a war over water - unless Ethiopia can agree a deal with Egypt and Sudan.
Join the BBC's Africa correspondent Alastair Leithead and his team, travelling from the Blue Nile's source to the sea - through Ethiopia and Sudan into Egypt.
Flying high above the river and its waterfalls, you will inspect the dam up close and take a sunrise balloon ride over Luxor as the story unfolds.
