Abbie’s husband walked out on her two months ago. She’s now a single mother of a two-year-old, fighting to keep her job and a roof over their heads. She’s up for a promotion, and she needs it, but the universe has other plans.

Faced with a long tailback on her daily commute, Abbie follows a car down what she thinks might be a way around the traffic. It’s a dead end, and she drives straight into a murder scene.

At first she’s willing to be a witness and help the police convict the high-profile killer, but after her son’s life is threatened, she pulls out.

What happens next is out of her control. She’s thrown into a world of lies, violence, and deceit; where not all the good guys are on her side, and her worst fears are used to manipulate her.

But even the toughest criminal is no match for a mother’s revenge.
