A bomb rocks West Hollywood. And with that, LA joins the brotherhood of American cities hammered by the harsh fist of terrorism. A dozen murdered and numerous injured, including Frank Grace, a cop with a checkered past who once again is at the wrong place at the wrong time.

While recuperating, Detective Grace is handpicked by the police chief to do whatever necessary, legal or not, to swiftly apprehend the perpetrators. Chief Kent refuses to stand by while his city burns and his legacy is tarnished amidst the growing rage and prejudicial violence spreading across Los Angeles.

Along with his principled partner, Michelle Santana, Frank begins to unravel a perilous network of deceit, dishonesty, and distrust. A fellow officer with a shady history, a judge with a dubious past, and a high-class prostitute are abducted. A homeless man is murdered. All are seemingly unrelated to the terrorist attack. Or are they? Frank Grace doesn't think so.

With the feds breathing down his neck, the chief pressuring him, the knowledge that even longtime allies can't be trusted, and another attack looming, Frank realizes time is running out. Exposing the truth may further damage his already-tainted reputation, end his career, and cost him his life. Is he just a pawn in someone else's game?
