Dawn Oâ€™Keefe (Jess Weixler) is a teenage spokesperson for a Christian Abstinence group called The Promise. She attends groups with her two friends, Gwen (Julia Garro) and Phil (Adam Wagner). One evening after giving her speech talking about the purity ring those in the group wear and what it means, she is introduced to Tobey (Hale Appleman) and finds him attractive.
The four begin going out as a group, and Dawn has fantasies of marrying Tobey, although after acknowledging the attraction they agree that they cannot spend time together. Soon after they give in and meet at a local swimming hole. After swimming together, they go in to a cave to get warm and begin kissing. Tobey then forces himself on Dawn; in the panic her vagina bites off his penis. Horrified, he stumbles away and she flees the scene. After a Promise meeting, she meets her classmate Ryan (Ashley Springer) at a dance; they talk, and he drops her off at her home.
Dawn researches “vagina dentata” and realizes she may have it, then she visits a gynaecologist, Dr. Godfrey (Josh Pais) in an attempt to find out what is happening to her. Finding out that she is a virgin, he attempts to take advantage of her by saying he is performing a test, when what he is really doing is molesting her. She panics and her vagina bites off the fingers on his right hand. On her way back, she sees someone driving in Tobey’s car, and she goes back to visit the pool. When she gets there she sees the police bringing up Tobey’s body. At home, her ill mother, Kim O’Keefe (Vivienne Benesch) collapses, Dawn’s stepbrother, Brad (John Hensley) and his girlfriend Melanie (Nicole Swahn) ignore her and continue to have sex while she lies on the floor. Kim is taken to the hospital.
Dawn cycles away from home, but her bike sustains a puncture, so she begins hitchhiking. She gets a lift from an old man (Doyle Carter), but when she reaches the next gas station and tries to get out, he locks the doors. He licks his lips as if to ask for a sexual favor to release her; Dawn hesitates, and then looks towards the camera -and the old man- with a seductive smile.
