The Dead have conquered the Earth, devouring and destroying everything in their path as mankind is brought to the edge of extinction. After battling their way out of Baghdad, across the Middle East and in to Europe, Marcus and what is left of his team, are close to reaching their final objective. Now, they must continue their struggle against the hordes of rotting corpses that stand in their way as they travel the wasteland that had once been their home. As Marcus and his men press on, his brother, Steve, continues to hold together the band of survivors within the walls of the Safari Park. With danger all around, he soon discovers that they are fighting against more than just the un-dead. **

The world is dead. The army of walking corpses have conquered all before them and only small pockets of humanity remain. As the cities slowly crumble, the survivors are facing their first winter in the new order while an immense horde of festering un-dead surrounds their walls, threatening their continued safety. While Steve and Marcus struggle to keep their small band alive, a new threat looms over the horizon; a danger that no one could have perceived, and more devastating than the 'dead plague'.
