When a man who appears mentally unstable holds a group of people hostage and dies in a shootout with the FBI, Special Agent Lucy Kincaid is assigned to investigate what happened. Up until two months ago, McMahon was a respected scientist - then his wife left him, he lost his job, and he was arrested for assaulting a former colleague. The one person who might have answers - his research assistant - has disappeared. While Lucy is investigating this bizarre case, her husband Sean is on top of the world: his son Jesse is visiting for the summer. They are having a blast, until someone follows them. Sean is positive that the surveillance is connected to Jesse's step-father - a man who had once laundered money for a violent drug cartel. But when Lucy and Jesse are run off the road, they begin to wonder if the attack is connected to Jesse... or Lucy's current case. Nothing is what it seems - not the McMahon investigation orthe car accident. As Sean and Lucy dig deep into the lives of everyone involved, one thing becomes clear: If they don't find the truth fast, everyone they care about is in danger...
