Reporter Lowell Bergman talks to political commentators, journalists and those caught in the crossfire about the phone-hacking scandal that has seen several journalists arrested.
Bergman tells of the battle for the future of News Corporation, particularly in the US, and the impact on Murdoch's reputation.
The program opens with the sound of a ringing phone, followed by an answering machine. This is followed in short order by The Guardian's Nick Davies telling the camera that the first he heard of the phone-hacking scandal was when somebody called him from out of the blue, according to the Montreal Gazette.
Davies broke the story for the British daily newspaper The Guardian, a rival to Murdoch's now-defunct News of the World.
"It's not just a story about journalists behaving badly," Davies tells Frontline."It's a story that immediately, by fluke, takes you into not just the most powerful news organisation in the country, but also the most powerful police service in the country, and the most powerful political party. And in all of these, you find them behaving wrongly, illegally, immorally," Davies is quoted saying in the show. AAP RY
