With a fortune estimated at over $ 60 billion, Warren Buffett is a billionaire like no other. Now, 86, the legendary investor lives in a modest house in Omaha and continues to drive his car every morning to his office at Berkshire Hathaway, the fifth largest public company in the world. But even more surprising than his modest lifestyle is his exemplary moral code. The same principles of decency and integrity that helped him build a fortune led him to make the greatest philanthropic donation in history. Directed by award-winning director Peter Kunhardt, this documentary features the evolution of an ambitious Nebraska boy obsessed with numbers that has become one of the richest and most respected people in the world.
