For the past five decades the Aga Khan has been the spiritual leader and Imam of the Ismaili Muslims in a world that has changed dramatically. From the end of colonialism and the expulsion of the Asians in Uganda to the fall of the Iron Curtain and 9/11, the Aga Khan has struggled for a common humanity in a divided world.

And the divides are not just East and West but also within the Muslim World itself. The Ismaili Muslims have been persecuted in the past and their history has shaped them and their philosophy.

Who is the Aga Khan? Who are the Ismailis? And what do they have to say about our post 9/11 world? The Aga Khan vehemently says we are facing a clash of ignorance - not of civilizations or even of religions.

As the first documentary on the Aga Khan in almost fifty years and with a rare and exclusive interview with him, this is the film that needed to be made.
