In 1906, William J. Seymour, a one-eyed black pastor from Louisiana, son of a slave, journeyed by train from Houston to Los Angeles, only to be locked out of the church that sent for him. He turned to prayer and God's answer was The Azusa Street Revival. It shook the very foundations of the American church. People reported speaking in tongues, new denominations were formed, and the Charismatic Movement was born. This documentary looks, in depth, at the inception of this movement and the mystery and controversy surrounding some of its beliefs.
