District Attorney David Franks is young, charismatic, ambitious – with his eyes fixed firmly on the governor's office. A relentless careerist, he times all his best moves to break on the evening news. By contrast, David's idealistic, relentless, no-holds-barred chief investigator, Mark Camacho, is a throwback who lives for the law and won't stop short of the truth. Colleagues one minute and opponents the next, David and Mark lead a group of remarkably true-to-life professionals – and deeply flawed personalities – in the pursuit of justice. The crimes they investigate and the suspects they break are headline-making career-builders. But self-interest, grudges, private vendettas and illicit affairs simmer just below the polished public face of this District Attorney's Office.
