Arrested for violating his parole, guitar-playing car thief, Wesley Benfield, is sentenced to a half-way house in the middle of the Bible belt. Ned Sears, who runs the house is an eccentric zealot, currently forming his own hymn playing band, who recruits young felons based on their musical talents. Wesley and the motley assembly of lawbreakers are confined and condemned to playing "church music" to retirees and grade schoolers. Then Wesley meets Vernon, an autistic savant whose rocking blues piano playing electrifies them all. Vernon provides the band with the spark it needs--and together, with singer Shanita Scott, they form the red hot Killer Diller Blues Band. Now, all they have to is break the law one more time.
