The cocky high-school jock, the ugly duckling who turns into a swan, the stuck-up cheerleader---all the clichés of teen movies are skewered in this uproarious parody of the genre. Chyler Leigh stars as a plain-Jane who's transformed into a prom queen by a hunk (Chris Evans) who's only doing it because of a wager he made with his pals. Jaime Pressly.
