When a Navy vessel comes across a yacht in distress in the middle of the vast Indian Ocean, Captain Danial Tengku orders his ship to rush to its aid. On board the yacht is a British couple: a horribly injured man, Jake, and his traumatized wife, Virginie, who breathlessly confesses, “It’s all my fault. I killed them.” Trembling with fear, she reveals their shocking story to Danial, and it will be up to him to determine just how truthful she is. But when his crew makes a shocking discovery, Danial realizes that if he doesn’t act soon, they could all fall under the dark spell of the island.
