It is a documentary style program that relies on interviews with former White House Chiefs of Staff and how they performed their job as gatekeeper for the President. It was pretty interesting to hear how when Obama took office the Chief of Staff for Bush invited all of the then living former Chiefs of Staff to meet with Rahm Emanuel and to give him some advice on how to do the job. it also had interviews with them about how they handled and responded to scandal and crisis. It was interesting stuff.
