In one small town, a legend passed around for over a hundred years is about exact its revenge…
Maeve Blackwood and her friends need a break after their exams. And what better place than Sapphire Cove, a secluded island without any adult supervision.
Their relaxing vacation is interrupted by a dangerous storm that takes away their only way home. In desperation, they find a cabin on the island that’s home to a local lore about a witch who was trapped within a stone wall.
When they test the legend, they are sorely surprised when they are faced with a beautiful and fiercely powerful witch hell-bent on revenge.
