In 2003, veteran AMS agent James Taylor and rookie Kate Green are reviewing intelligence in the fifth basement of AMS's European headquarters when an earthquake collapses the walls and traps them inside. Several days later, stranded and awaiting backup, James's PDA alerts them to an emergency: security cameras show the building overrun with creatures. Fighting their way out, they uncover a classified plot to launch nuclear missiles at targets worldwide—with less than twenty-four hours on the clock. James has long suspected the 2000 Goldman incident is not truly over, and now the evidence suggests he was right.
