Doomsday

Set a few decades in the future, after a deadly virus infected Scotland. The Brits built a high wall to quarantine the whole of Scotland, and waited for the virus to take its toll. Now, 30 years later, the virus has surfaced in London, and remote cameras are showing activity in Glasgow. The Brits decide to send a crack team to investigate. Their mission: find a cure in Scotland within 48 hours. Once there, however, they find two armed factions fighting with each other, and now also with them. They've only got 48 hours to find the cure and get out ... alive.
