Karen Donovan is a woman who has it all: a successful business, a great relationship with her mother and sister, and an adoring 12-year-old niece, Ashlee. But when she and Ashlee are caught in the middle of a robbery gone wrong, Ashlee ends up comatose in the hospital. Karen tells Detective Frank Newman that she recognized one of the men involved in the robbery, Ray Martinez. When Newman is unable to break his alibi, however, Karen decides to go talk to him herself. But when Ray pulls a gun on Karen, she’s forced to kill him in self-defense, an act which launches her onto a path of confrontation with the other members of the robbery crew. Frank begins to grow suspicious that he might have a vigilante on his hands. When Bobby, the head of the crew behind the robbery, realizes that Karen is on a path that will lead her directly to him, he lures her to an empty house to confront her. Bobby reveals not only that he is the guy behind the robbery, but was also involved in the death of her brother ten years ago - and that he now plans to finish off Karen and her niece. Now, Karen finds herself locked in a desperate struggle for her life - and justice for her family.
