Now a grown woman, Camille sets out with her friend James (Clinton Roper Elledge) to hopefully find some answers.

Natalie (Elisabeth Harnois) is high school royalty, but her queen bee status falls apart when she falls for the new guy at school. Although Keith (Jesse McCartney) ignores her at first, they soon become friends — even though Natalie suspects that Keith has something to hide. As the free-spirited Keith shows Natalie how to embrace what life offers, they grow closer — until a secret tests the bounds of their relationship
