When a horde of towering creatures wreaks havoc on FDR's Washington D.C., no one--including the president--knows where they came from. A desperate group of survivors make it to Fort Detrick, where they seek refuge from the devastation. They think they're safe there. After all, It's FDR's state-of-the-art maximum-security facility. But relief turns to horror, as they find they've locked themselves in with a more hideous threat than the one they left behind.
