Dawn O’Keefe (Jess Weixler) is a teenage spokesperson for a Christian abstinence group called the Promise. She attends groups with her two friends, Alisha (Julia Garro) and Phil (Adam Wagner). One evening after giving a speech about the purity ring worn by members of the group, she is introduced to Tobey (Hale Appleman), who she finds attractive. The four begin going out as a group. Dawn has fantasies about 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 into a cave to get warm and they begin kissing. Dawn becomes uncomfortable and tries to get Tobey to go back outside, but Tobey becomes more physical and aggressive. Dawn panics and tries to push him off, which results in Tobey growing more infuriated. As he shakes Dawn she smacks her head on the ground and, while she is dazed, Tobey takes the opportunity to begin raping her. Dawn fights back and inadvertently bites off his penis with her vagina. A horrified Dawn 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.
