Something very bad is happening behind the walls of the US embassy in Baghdad.
A strange and terrible virus is turning ordinary people into primitive killers, and all attempts to contain the outbreak have failed. With the violence spreading and the body count rising faster than the Iraqi heat, Washington turns a deaf ear and a blind eye to the crisis. Once again, American lives are about to be sacrificed for political gain.
When the stench of betrayal hits Baghdad, the survivors realise they must fight their way out of the compound if they want to live. With the infected on the loose and hunting in murderous packs, escape for the dwindling band of Delta Force operators, Marines and terrified diplomats will not be easy.
But it's about to get much worse - the embassy itself is turning against them.
Deep beneath the compound, automated defence systems are coming online, a highly classified arsenal of weapons designed to kill anything and everything on an industrial scale.
