High school senior Cookie Vonn's post graduation dreams include getting out of Phoenix, attending Parsons and becoming the next great fashion designer. But in the world of fashion, being fat is a cardinal sin. It doesn't help that she's constantly compared to her supermodel mother and named after a dessert. Thanks to her job at a fashion blog, Cookie scores a trip to New York to pitch her portfolio and appeal for a scholarship but her plans are put on standby when she's declared too fat to fly. Forced to turn to her BFF for cash, Cookie buys a second seat on the plane. She arrives in the city to find that she's been replaced by the boss's daughter, a girl who's everything she's not: ultrathin and super rich. Bowing to society's pressure, she vows to lose weight, get out of the friend zone with her crush and put her life on track .
