Callan O'Malley embodies everything that should scare Terri Barclay. O'Malley freelances as a gun runner for a biker gang, the dark secrets of her past influencing her present. Thrown together by circumstance and unexpected complications of living in the biker world, the women's lives are turned into chaos. Loyal friends of past and present, add to the mixture which brings the two women closer than they ever thought possible. Terri, however, is hiding her own secrets. Secrets that could very well get her--or O'Malley--killed. Terri must walk a fine line between what she now wants and what she is forced into by her sense of duty. She must redefine her approach on life and love and acknowledge that not everything is as black and white as she once believed. She soon discovers that living on the edge with a woman such as O'Malley can be an exciting yet dangerous place.
