In 2008, an unknown killer virus, known as the "Reaper virus", has infected the country of Scotland. Unable to contain the outbreak or cure the infected, the British government builds a massive 30-foot wall that isolated Scotland from the rest of Great Britain. Whilst the quarantine was deemed a success, the extreme method employed by the government destroys diplomatic and economic relations between the UK and the rest of the world. Now a pariah state, the UK collapses into a dystopia, rife with unemployment, civil unrest and extreme economic turmoil.
