'The Flu That Killed 50 Million' - Tuesday 25th September 21:00 BBCTWO.
It is 1918 and the end of World War 1. Millions have died, and the world is exhausted by war. But soon a new horror is sweeping the world, a virus that will kill more than fifty million people - the Spanish flu.
We created the maps and graphics showing how the virus spread across the globe for this one-off special.
Narrated by Christopher Eccleston.
