The Scotsman has gone into detail on the plot for "Doomsday," the currently filming next project of Director Neil Marshall ("The Descent," "Dog Soliders").

Here's the official breakdown: "Scotland has been cut off from the outside world for about 30 years, following the outbreak of a deadly virus, caused by genetic tampering.

Hadrian's Wall has been rebuilt to keep the Scots out of England. But the Scots have a cure for the virus, and when England is threatened by a new outbreak, a crack military team goes over the wall to get it, led by Rhona Mitra.

Marshall himself adds some more details to the story - "She goes through from the wall up to Glasgow and then farther north. The farther north she gets, the more back in time she goes. It's like a Heart Of Darkness journey.

There's a Kurtz character (Malcolm McDowell) running a feudal society and living in a castle. He used to be a scientist - he's the guy who found the cure and he's taken on this kind of God-like stature up there."
