Photojournalist Alex Graham bears witness to disasters that we should never forget. So when a dam breaks in Colorado, she goes on site - not only snapping pictures but also digging for survivors. Drawn off to a remote part of the site, she stumbles onto something nobody was meant to see: a man with a rifle, a helicopter crash, and an avalanche she believes buried evidence that the tragedy was far from natural. When Alex wakes up in a hospital with an impaired memory, she vows to find the truth - and acquires a bodyguard whose checkered past has made him the target of an unseen assassin. But Judd Morgan is the only chance of protecting Alex from an enemy who never misses.
