Belly returns to the seaside villa as the same overlooked girl she once was. At a pool party, she is publicly humiliated with old photos projected on screen, and her necklace is torn off. Conrad drapes his coat over her, while Jamie dives into the pool to retrieve her necklace. Over the summer, both brothers lose their hearts to her uncontrollably. Yet the necklace hides a key, which unlocks an old box containing a long-standing covenant that ties Belly, the two brothers, and the seaside villa together. This summer, she will no longer wait to be chosen. She will take charge of her own life and choose for herself.
