Lake Wobegon - where the women are strong, the men are good looking and all the children are above average - has become America's collective hometown, visited weekly for the past 40 years on a fictional radio program that creates bona fide nostalgia. With his "Prairie Home Companion," Keillor became our national philosopher, filling the empty shoes of Will Rogers and Mark Twain, through his running commentary about the human condition and the social politic. With biting wit, a quirky perspective and an uncanny ability to home in on the pulse of America, Keillor's themes and characters are somehow familiar to us all. For more than a year, AMERICAN MASTERS followed this great raconteur - and his motley crew of actors, musicians and technical staff - as he criss-crossed the country, broadcasting, recording and revealing himself.
