Melissa Martin gets dumped by long-time boyfriend and male model, Derrick Winters, after she gains twenty pounds. With the help of a magical stone necklace, she hopes to turn his head again. Using the necklace's powers to make her body appear slim again, Mel gets caught in a tug of war between two men. Derrick wants the apparently slim-again Mel back in his bed while Jason, another male model, yearns for the voluptuous Connie, Mel's supposed twin sister with the plus-size body. As if she doesn't have enough trouble pretending to be two different women with two different bodies, a snooty female model will do anything to sabotage her efforts to win back Derrick's heart.
