In the 1100 churches of Indianapolis, we see bewildering multiplicity of Protestantism. Churches with the seating and styling of deluxe first-run theaters. Services conducted with the professionalism of television spectaculars. And congregations that occupy every seat at four staggered services every Sunday. All are features of the US church-going boom. We discover that religion is not in a state of apathy in America; in some quarters it is decidedly big business.

Traces the Indian religious experience in two highly contrasting locations: the bustling city of Benares where millions come to bathe in the holy waters of the Ganges, and the small village of Bhith Bhagwanpur, unvisited except by professional story tellers and itinerant priests. The film concentrates its attention on the Hindu approach to God. But which God? For there are 330 million of them.

To Sri Lanka (Ceylon) and India to discover the type of Buddhism practiced throughout southeast Asia. Among those we meet are Buddhist monks-including one American, school children, novices and housewives.

It is said in Islam that every child is born Muslim by nature: he has the belief in his heart of one God. Over 400 million people profess Islam, and its numbers are said to be growing. In this program we travel to Egypt to explore the Islamic experience in an oasis village 50 miles from Cairo at a wedding, in the market town of El Fayoum for dawn prayers, and in Cairo itself.
