The music is as hot as the sexual tension between Ruby Delacroix and the new white singer, BIlly Dupre, at her popular juke joint in Louisiana. When Ruby's husband deserts her and their rebellious teenage daughter, Ruby takes on a vulnerability that becomes too much for the married Dupre to resist. Even though their affair could be a fatal mistake in the racist South of the early 1960's, the couple cannot resist temptation.
