Thomas and Alexander had been out celebrating their second year of being together. When they finally got back to their secluded home in the woods, they find that their beloved dog, Jasper, seemed to have jumped the gate and ran free. They'd never believed the stories that everyone told of the entities that crept in the vast woods. Most didn't. But when they venture further and further into the forest, they realize how wrong they were.
