When Dracula is called away on "official vampire business," it is a chance for his teenage daughter, Mavis, to show her father what she can do. Assisted by her friends Hank N Stein, Pedro and Wendy Blob, she puts into motion her ideas about how to run Hotel Transylvania. It's not all fun and games, though, when Aunt Lydia, Dracula's older and much meaner sister, enters the picture. She pushes for more order and tradition at the hotel, curtailing Mavis' plans to let loose with her friends. The animated series is based on 2012 feature film "Hotel Transylvania."
