Left of the Dial

The provocative, controversial saga of the Air America radio network is the subject of this "America Undercover" documentary. The ambitious effort to counter the dominance of conservative talk radio suffers a nearly total collapse after a highly publicized scandal and disappointing returns in the 2004 elections, but network stalwarts (including satirist Al Franken) use the setbacks as inspiration for an even greater resolve. 98 min. Widescreen (Enhanced); Soundtrack: English.
