Witness one of the worst debacles in American military history. Enter Abu Ghraib. You've seen the photographs on the nightly news: the naked prisoners, the pyramid of degraded captives, and the infamous thumbs-up grin of the young female corporal standing guard over them all. Now, come inside and see the true story of the men and women who crossed the thin line between interrogation and torture. Errol Morris's award-winning documentary takes you behind the bars of the 21st century's most infamous prison, and the acts that forced a president to apologise to the world.
