Exploring the complexities of the American-Iranian relationship in the wake of Sept. 11 and President Bush's inclusion of Iran in what he called an "Axis of Evil" in his State of the Union address. Iran, governed jointly by conservative mullahs and reformist politicians, is a "schizophrenic state," says producer Neil Docherty, who interviews representatives from both camps. "It's way too big to ignore and way too difficult to really deal with." Also interviewed: Sen. Joseph Biden (D-Del.), who chairs the Senate Foreign Relations Committee; former CIA chief James Woolsey; and journalist Elaine Sciolino.
