On the beautiful and windswept island of Tresco, two worlds live side by side. The wealthy visitors come by helicopter to stay at their lavish time-share properties. The estate staff travel by boat, and work all hours to keep them happy, to keep the money flowing in. But while the blue skies and savage waves make the island seem a wild paradise, under the surface the inhabitants are concealing more than they dare reveal. As black clouds come rolling in and a storm hits the island, truths and rumours begin to tumble out, wreaking terrible damage. In the midst of the tempest, two women are attacked and one goes missing. The secrets of this fragile community can no longer be hidden if it hopes to survive. The islanders must finally reveal what they did in the storm, no matter the cost.
