Mary is a good Christian girl who goes to a good Christian high school where she has good Christian friends, mainly Hilary Faye, and a perfect Christian boyfriend, Dean. Her life seems perfect, until the day that she finds out that Dean may be gay. After "seeing" a vision of Jesus in a pool, she does everything in her power to help him turn straight, including offering up her virginity. But none of it helps because Dean's caught and sent to a "degayification" center and Mary ends up pregnant. It's during her time of need that she becomes real friends with the school's set of "misfits," including Cassandra, the school's only Jewish girl; Roland, Hilary Faye's wheelchair-bound brother, and Patrick, the skateboarder son of the school's principal, Pastor Skip; whilst Hilary Faye turns her into a social outcast.
