In the hushed quiet of early morning Manhattan, in front of the towering bronze doors of Saint Patrick’s Cathedral, a young woman holds a sign that reads: HELP ME. For one FBI agent, a madman’s terrified hostages, and an entire city, a long and harrowing day is about to unfold.
 
The hostage taker’s identity is unknown. But he knows who FBI agent Eve Rossi is --- and everything about her past. Along with her presence, he demands five witnesses: ordinary people with some hidden connection. Defying her superiors, Eve begins a deadly dance with an adversary whose intentions are surely sinister, whose endgame is anything but certain, and whose cunning keeps him one step ahead at every turn.
 
As Eve manages a taut hostage situation, she relies on the combined skills of her team --- a secret unit inspired by France’s most notorious criminal and made up of ex-convicts with extraordinary talents, oversized egos and contempt for the rules.
 
Eve is up against a rapidly ticking clock. But the dangerous man calling the shots has a timetable of his own --- and a searing question for his targets: What are you guilty of? As shocking revelations surface, so does another crisis nobody could anticipate --- one not even Eve and her team may be able to stop.
