Unsettled by a series of painful memories, Cadence tries to enjoy what's left of her summer – even if it means distracting herself with a potentially dangerous stunt. Despite her best efforts, she remembers a stormy day from Summer 16 when rising seas and frustrations threatened every Sinclair, exposing the family's darker side and forcing Gat and Cadence to confront their unspoken feelings.

Unable to continue keeping secrets from her, Gat finally opens up to Cadence about his perspective on the island – one that doesn't always reflect the fairy-tale nostalgia of her own experience. While they head into town in search of answers, Gat recounts his memories of an honored Sinclair tradition – Tipper's Lemon Hunt – and the unplanned visit from his mother that made him question everything.
