Former high school sweethearts, Haley (Kebbel) and Rob (Roerig), bump into each other while at an excavation site for an archeological research team, currently in the field at Great Smoky Mountains National Park. Rob immediately tries to reconnect with Haley and rekindle their romance, but Haley isn't quite over Rob's betrayal. During their senior year, Haley had applied for a research grant that was awarded to Rob instead of her. The two have not spoken since, but now Haley is determined to remain professional as she and Rob work together at this exciting excavation site. The two eventually reconnect over their common love of nature and history, spending time together exploring the park. But when Haley finds pictographs in a cave that may lead to the existence of a mythical Cherokee diamond, Rob struggles to keep up with her adventurous nature. And to complicate their relationship even more, they discover they are once again competing for the same research grant. They work together and finally find the cave, and slowly realize that the journey is perhaps more important than the destination - and love is more valuable than any research grant.
