Tasia McFarland is a washed-up country-pop singer desperate for the break that will get her topping the charts again. The tabloids have raked over every part of Tasia's rocky life, following every high and low -- her addictions, her breakdowns, her increasingly erratic behavior -- and every broken relationship. The highlight of this lowlight reel: Tasia McFarland is the ex-wife of the president of the United States. So when Tasia writes a song with politically charged lyrics, people take note and her star begins to rise anew. In the opener of her comeback tour, she is lowered into a stadium on a zip line, and as helicopters fly overhead, she fires her prop Colt . 45 at the fireworks-filled stage. Tasia is riding high. Until she's killed by a bullet to the neck before the shocked crowd of forty thousand. When video can't prove that the shot came from Tasia's own Colt . 45, and the ballistics report comes up empty, the authorities call on forensic psychiatrist Jo Beckett to do a psychological autopsy and clean up the potential political disaster. But as Jo sifts through the facts, she only finds more questions: Was Tasia's gun loaded? Did she kill herself in one last cry for attention? Were her politically charged lyrics the rantings of a paranoid woman losing her grip, or warnings from a woman afraid and in danger? For Jo, pouring over Tasia's past becomes a race to extinguish the conspiracy rumor mill before it incites a level of violence that reaches America's highest corridors of power -- and tears apart the very fabric of our nation.
