Legend says the cliffs by the seaside town of Edge are riddled with smugglers' tunnels, and that gold is stashed in their caves. Freya and her best friend, Lin, love searching for treasure on the beach, but they steer clear of the dark and twisting tunnels. It'd be easy to get lost in there, and Freya's sure she can hear voices echoing from them when the wind blows. Then a mysterious woman moves into Freya's granny's B&B and soon everything that Freya loves about Edge is under threat. It's time for Freya to face her fears. Can she strike gold before time runs out for her town?
