How do you lead a nation to independence? In 2007 this was the question faced by Alex Salmond, leader of the SNP, after the political party toppled half a century of Labour Party dominance in Scotland, and was, for the first time, able to form a minority government in the Scottish Parliament. How do you defend Scotland's place in a centuries-old political union? This was the alternative question faced by Labour, the Conservatives and the Liberal Democrats.

'Yes or No: Inside the Indyref' tells the inside story of the clash between these two opposing political forces and the politicians and pollsters, IT specialists and bloggers, playwrights and historians who dedicated themselves to securing victory for their opposing vision of Scotland's future. They used pioneering IT technology, in-depth political polls, scare tactics and even an old 'Irn Bru' crate to get their message across to the public.
