A strange old woman allows a teenage runaway and a young orphan to stay in an abandoned house that overlooks the sea. However, when a menacing entity threatens their new home, they must band together and face their fears to save it.
Everything seems to be changing for the better at Hotel Transylvania... Dracula’s rigid monster-only hotel policy has finally relaxed, opening up its doors to human guests. But behind closed coffins, Drac is worried that his adorable half-human, half-vampire grandson, Dennis, isn’t showing signs of being a vampire. So "Vampa" Drac enlists his friends Frank, Murray, Wayne and Griffin to put Dennis through a "monster-in-training" boot camp.
