Deep in the Iraqi desert, a team of elite Delta Force operators assault a secret pathogen lab that threatens all human life on the planet.
After a vicious battle the threat is contained, and the world can breathe again.
Or so it believes.
Inside the US Embassy in Baghdad, one of the Delta team is quickly succumbing to a mutated virus, one that is stripping him of his humanity. When he finally emerges from the shadows, his only instinct is to inflict murderous violence on anything that crosses his path.
As containment turns to chaos behind the embassy's blast-proof walls, a desperate group of State Department personnel and Delta Force operators must survive any way they can until help arrives, help that has been quietly denied to them by a corrupt Washington cabal.
Trapped behind the walls of the embassy, the compound filled with primal killers, there are only two choices for those untouched by infection.
Stay and die.
