Ronald Reagan has been off the world stage since his letter to Americans announcing that he suffers from Alzheimer's. But his impact on the U.S. and the world lives on. In a series of intimate interviews, including Nancy Reagan and the Reagan children--Patti Davis, Ron Reagan, and Michael Reagan--we present the private stories of a very public man. Fellow leaders, including Mikhail Gorbachev, also appear, along with intimates who tell behind-the-scenes stories about key turning points.
