"Mavis's friend Hank has a problem. He is a Frankenstein monster, which means that his body comes apart in pieces. His friends think it is hilarious, but Hank is tired of being a monster and wishes he was normal. Mavis tries to help him make his wish come true, but turns him into a human by mistake! Everyone at Hotel Transylvania is terrified of humans! If she can't find a way to turn him back into a monster--and fast--he'll have to leave the hotel and will be stuck as a human...forever!"
