Christian High School student Mary (Jena Malone) will have her world turned upside down when her boyfriend Dean (Chad Faust) reveals that he's gay. Try as she may, Mary can't pray...or sleep...the gay away. Much to her surprise, Mary discovers she's pregnant. Ostracized by her holier-than-thou friends, led by the pious Hilary Faye (Mandy Moore), Mary will find acceptance from kindred spirits: the school's geeks, including the wheelchair-bound Roland (Macaulay Culkin) and Cassandra (Eva Amurri).
