Four years after Sloane's return, the marina is thriving — expanded, renovated, and fully reconciled as a three-way partnership between Sloane, Isla, and Faye. Then a late-season hurricane, the worst to hit the coast in thirty years, tears through Amber Cay and devastates the docks, the beach club, and half the town's waterfront businesses in a single night. The season follows the brutal, unglamorous work of recovery — insurance disputes, structural rebuilding, a temporary closure that threatens the marina's survival for the first time since season one — while old fractures resurface under the pressure. Beckett, having stayed in season three, must decide if he regrets it as the physical toll of rebuilding mounts. A wealthy former Amber Cay summer resident, Camille Ashworth-Reyes, offers a rescue investment with strings that echo Graham Whitlock's original offer four years earlier, forcing Sloane to confront whether she's actually changed or just gotten better at telling herself she has.
