The New York Museum of Natural History is built over a subterranean labyrinth of neglected specimen vaults, unmapped drainage tunnels and long-forgotten catacombs. And there's something down there. When the mutilated bodies of two young boys are discovered deep within the museum's bowels, Lieutenant Vincent D'Agosta of the NYPD fears a homicidal maniac may be at large. FBI agent Aloysius X.L. Pendergast believes they may be facing something much worse. As the death toll mounts, and with the opening of the museum's new 'Superstition' exhibition just days away, the two men must work together to prevent a massacre.
