After losing his wife, Evan Francart is depressed. He has an axe to grind with the pharmaceutical company that jacked up the price of her medications, but feels powerless against a billion-dollar corporation. Then he meets Cassandra. She shows Evan a way to both end his life and become a hero. With her guidance, Evan interrupts a company board meeting and blows the building sky-high. As FBI agents Susan Chamberlain and Michael Godwin discover, Evan is the first of many. Ninety-nine more like him wait anonymously in the wings, their targets just as personal as Evan's: the prosecutor who lets rapists walk free, the inept surgeon who maims patients yet keeps operating, the phony evangelist preying on those seeking solace... and that's just the beginning. Will the FBI unearth Cassandra's identity before all 100 have carried out their plans?
