Fifteen year old Kirstie and her Mom win an all expenses paid trip to a five-star resort for a few weeks over the summer. There are so many activities for Kirstie to choose from that it's almost overwhelming, but trying new things she meets new people. She meets five teenage boys (one of them is 12 but that's practically a teenager, geez) and goes on to have such an amazing few weeks that the group promise that they'll come back again next year. Kirstie doesn't go back, she can't afford to, but it was a stupid heat of the moment promise that none of them will be able to keep anyway, they were teenagers, it was impossible. Fast forward ten years and Kirstin's yearly work conference just so happens to be taking place at 'that' resort, the one where she had the most amazing summer. And to her complete surprise she finds out that Scott, Mitch, Matt, Kevin and even Avi have been coming back to this place every year, meeting up just like they'd promised they would. What happens now that Kirstie's finally made her way back too?
