Journalist Justine Goodman, stifled by new motherhood, surrenders to an obsession with Project Nemesis—an all-women group of eco-anarchists set on dismantling dirty energy companies. She risks everything to gain entry into their inner circle, but tragedy strikes before she can even begin to savor her involvement.

Zoe Rasmussen, wearied by her role as energy magnate Phil Rasmussen's wife, clings unhappily to her situation for her daughter's sake. When grief-stricken Justine, armed and unhinged, appears with a demand, Zoe is torn between terror and excitement. But Justine's actions have unwittingly attracted dangerous forces, and as these women hurtle towards collision, they each face the choice: uphold what's right, or risk shattering their lives.
