Five years ago, FRONTLINE and The New York Times joined forces to investigate death and dismemberment in one of America's most dangerous industries -- the iron pipe foundry business. One company stood out, the McWane Corporation. It had more health and safety violations than all of its competitors combined, and there were a number of environmental violations as well. In the five years since our original broadcast, federal prosecutors obtained indictments against and juries convicted the company in five cases in four states. Today McWane says it has made a dramatic turnaround and that worker safety and environmental protection are now high priorities. FRONTLINE revisits its original broadcast with correspondent Lowell Bergman who then reports on what has changed at McWane and whether the company has become a less dangerous business.

In the wake of yet another hard-fought and bitter presidential campaign, FRONTLINE presents a spirited and revealing biography of Lee Atwater, the charming, Machiavellian godfather of modern, take-no-prisoners Republican political campaigns. Through eye-opening interviews with Atwater's closest friends and adversaries, the film explores the life of the controversial political operative who mentored Karl Rove and George W. Bush, led the GOP to historic victories, and wrote the party's winning playbook. The story tracks Atwater's rise from his beginnings in South Carolina as a high school election kingmaker all the way to the White House and his subsequent battle with cancer and final search for forgiveness and redemption. To Democrats, Atwater was a political assassin who one Congresswoman dubbed "the most evil man in America," but to Republicans he remains a hero for his deep understanding of the American voter and his unapologetic vision of politics as warfare.
