Visiting her cousin Marjorie (Veronica Cartwright), sweet-but-dull Bernice (Shelley Duvall) is transformed into a smooth-talking man-trap by her vampish kin. However, the 'make-over' works too well, Bernice becomes the belle of the ball, captivating every boy's interest -- even Marjorie's boyfriend Warren (Bud Cort). One of the best screen translations of F. Scott Fitzgerald's literary work, Bernice also includes the delightful supporting role performances of Dennis Christopher ('Breaking Away') and Polly Holliday ('Alice').
