Lizzie (Ashanti) is looking to have the perfect destination wedding thanks to her doting father (Cedric the Entertainer). But her carefully laid plans are thrown into disarray when her "man-of-honor", Marshall (Jonathan Bennett), brings his "ex-from-hell", Marie. It is going to take an all-out effort from Lizzie's friends and family to keep Lizzie from losing her mind as her "happily ever after" is faced with ruin. THE PLUS ONE is an uproarious and charming romantic comedy.
