Academy Award winner Jodie Foster stars as Erica Bain, host of a New York radio show whose life is shattered by a brutal attack that leaves the love of her life dead, her own body shattered and her sense of safety permanently destroyed. 

Now, when Erica's fear of her beloved city becomes too much to bear, she arms herself...

The first time Erica shoots someone, it is kill or be killed. 

The second time it is also self-defense ... or did she make a choice not to take herself out of harms way? 

The fear that once gripped her has become something else.

 And as stories of an anonymous vigilante grip New York, NYPD detective Sean Mercer pieces together the clues.

 With both Mercer and her conscience closing in, Erica must confront the possibility that her quest for justice has changed her into the very thing she hunts.
