FRONTLINE raises troubling questions about how America's financial institutions protect our savings.

Ten trillion dollars in Americans' retirement savings are invested in large and small accounts managed by banks, brokerages, mutual funds, and insurance companies. But whether your IRA or 401K will assure a safe retirement is largely a gamble. Building off reporting from the special "Money, Power and Wall Street," "The Retirement Gamble" reveals how fees, self-dealing, and kickbacks bring great profits to Wall Street while imperiling the prospects of a secure future for individuals. The film questions who has the consumer's best interests in mind and whether there is a better way to manage our retirements. FRONTLINE tonight at 9pm

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.

Victoria Falls is the largest waterfall in the world.

Cutting across the Zambezi River, bridging the countries of Zambia and Zimbabwe,  this awesome force of nature divides two natural worlds -- the tranquil meandering river above the cascade, and the raging abyss of the gorge below. The upper river is idyllic, running shallow through sandstone hills and meandering around islands and reed-beds where elephants, hippos, and crocodiles thrive. Between the two worlds are treacherous cliffs and thick, mossy rainforests fed by river mists, home to baboons whose lives change with the seasons. When the rains fall, the rivers swell and the falls thunder.  Tonight, NATURE takes us to see Victoria Falls...7pm

He wore a bullet proof vest to his consecration...

Gene Robinson is the first openly gay Bishop, and his flock is in the New Hampshire Episcopal Church...A man whose two primary passions are in direct conflict: his love for God and for his partner Mark. His consecration by the Episcopal Church in 2003, to which he wore a bullet-proof vest, caused an international stir. He becomes the focal point as American churches debate whether or not lesbian and gay people are equal to heterosexuals in the eyes of God, while the United States at large struggles with legal equality for gays and lesbians.
