Can disgraced FBI Agent Marsha O'Shea, slumming in the Sunshine State, stop her neighbor’s deranged ex-husband from shooting up a battered women’s shelter and become the next mass-shooter headline? A perfect storm of domestic violence, untreated mental illness and lax gun laws come together in the final deadly encounter. John A. Hoda takes a mighty swing how a person devolves into a deranged gun nut. As mass shootings fill the airwaves nightly, no journalist takes the time to see how the person became the mass-shooter. O'Shea is working on her own emotional issues following the death of her brother in Philadelphia. She is unsure if she will be able to return to her career once the facts surrounding his death are fulling investigated.
