The movie picks up where the previous installment left off, with Count Dracula (voiced by Adam Sandler) and his friends, including Frankenstein's monster (voiced by Kevin Hart), Wolfman (voiced by David Spade), and Mavis (voiced by Selena Gomez), enjoying a peaceful life at the Hotel Transylvania. However, a new threat emerges in the form of a powerful, Transformania-infused monster, which starts to turn the hotel's guests into...well, let's just say, not-so-friendly creatures.
