Eleanor (Shailene Woodley) is a modern-day Clarice Starling, a young investigator wrestling with the demons of her past, when she's called to the scene of a brutal crime--the work of a new and terrifying mass murderer. The police and FBI launch a desperate nationwide manhunt but are thwarted at every turn by the killer's enigmatic, unprecedented behaviour. Despite her relative inexperience, Eleanor is drawn deeper and deeper into the case, as she and her colleagues realise that she may be the only person, given her own tortured psyche, who can understand the mind of this singular killer and bring him to justice.
