 Elmer Gantry is a fast talking, hard drinking traveling salesman who always has a risqué story and a hip flask to entertain cronies and customers alike. He is immediately taken with Sister Sharon Falconer, a lay preacher whose hellfire and damnation revivalism has attracted quite a following. Gantry uses his own quick wit and knowledge of the bible to become an indispensable part of Sister Sharon s roadshow but soon finds that his past catches up with him in the form of Lulu Bains, now a prostitute. While Gantry seeks and eventually gets forgiveness from Sharon, tragedy strikes when she finally manages to get out of her revivalist tent and opens a permanent church.
