Bill Maher takes a pilgrimage across the globe on a mind-opening journey into the ultimate taboo: questioning religion. Meeting the high and low from different religions, Maher simply asks questions, like "Why is faith good?" "Why doesn't an all-powerful God speak to us directly?" and "How can otherwise rational people believe in a talking snake?" For anyone who's even a little spiritually curious, this divine entertainment will deepen your faith... in comedy!
