Tyrone (Danny Glover) is the proprietor of the Honeydripper juke joint. When business at the once-popular club begins to trail off and Tyrone hires unpredictable electric guitarist Sonny (Gary Clark Jr.) against his better judgment, Tyrone's last-ditch bid to draw in crowds during harvest time has surprising results that neither desperate Tyrone nor the ambitious Sonny could have ever anticipated. Blues guitarist Keb' Mo' co-stars in the film, which was written and directed by John Sayles.
