Leap of Faith (1992)

Jonas is a fraudulent faith healer, who uses all the tricks in the book to con the people attending his shows. Jonas and his team of helpers, including Jane who is in need of some romance, travel the country stopping at big towns and cities to put on their show. When one of the trucks breaks down in a small town, Jonas is quick to accept the challenge of making money in this town. His other goal is to seduce Marva, a waitress in the town, but she's a hard nut to crack, as is Will, the local sheriff who's determined to expose Jonas as a fraud.
