Eulis ‘Sonny’ Dewey is a preacher from Texas living a happy life with his beautiful wife Jessie. Suddenly his stable world crumbles: Jessie is having an affair with young minister Horace. Sonny gets enraged and hits Horace with a softball bat, putting him into a coma. After that he leaves town, takes a new name, ‘Apostle E.F.’ and goes to Louisiana. There he starts to work as a mechanic for local radio station owner Elmo, and Elmo lets him preach on the radio. E.F. starts to preach everywhere: on the radio, on the streets, and with his new friend, Reverend Blackwell he starts a campaign to renovate an old church.
