Lisa Kerry witnesses a private death squad attack street kids close to her bookstore. When the police take no action, she vows to purge Rio of the ruthless killers. To keep him out of the line of fire, she must quell her affection for the one man cut out to exorcise the demons of her past. Drawing strength and rage from the abuse she suffered as a young girl in a juvenile detention center, Lisa closes in on her marks.
Unable to get to the rich and powerful leader of the recreational killers, she enlists the older brother of one of her street urchin friends—a drug lord. Lisa's pursuit of justice spirals into a violent struggle to survive, for herself, her young charges, and the man she loves.
