Forrest Gibson has spent years trying to forget Shauna, the high school sweetheart who slipped away when they were nineteen, until a work trip to Las Vegas puts her across the table from him, engaged to someone else and days from walking down the aisle. One dinner is enough to remind him that no one else has ever come close, and he leaves determined to speak before it is too late. He flies back to stop the wedding and watches her walk down the aisle anyway. Then, six weeks later, she turns up in Newberry Springs with no ring on her finger and a job at his parents house. He still wants the future he always saw with her, but trusting her again means risking the same heartbreak.
