Count Dracula's (Adam Sandler) daughter Mavis (Selena Gomez) marries Johnny (Andy Samberg), and the couple have a son named Dennis (Asher Blinkoff), who befriends a werewolf pup named Winnie (Sadie Sandler). Nearing his fifth birthday, Dennis has yet to grow his fangs, which worries Drac that his grandson might not be a pure-blood vampire. Noticing the dangers of Transylvania, Mavis starts to consider raising Dennis where Johnny grew up, dismaying Drac.
Mavis and Johnny travel to California to visit the in-laws, Mike (Nick Offerman) and Linda (Megan Mullally), leaving Drac to babysit Dennis. Drac enlists his friends Frank (Kevin James), Wayne the Werewolf (Steve Buscemi), Griffin the Invisible Man (David Spade), Murray the Mummy (Keegan-Michael Key), and Blobby the Blob (Jonny Solomon) to help train Dennis to become a monster, to no avail.
Drac takes Dennis to a summer camp where he learned to hone his vampire abilities, to no avail either. Desperate, Drac hurls Dennis from a tall, unstable tower to pressure his transformation into a bat, but rescues him at the last second. The stunt is filmed by the campers and uploaded to the internet which eventually reaches Mavis and Johnny who hurry back to Transylvania. Mavis scolds her father for endangering Dennis and his inability to accept that he is human, promising to move out of the hotel after Dennis’ fifth birthday.
Mavis invites Vlad (Mel Brooks), her grandfather and Drac’s father, to Dennis’ birthday party. Dismayed, Drac has the partygoers disguised as monsters. Vlad arrives with his monstrous bat servant Bela (Rob Riggle) and meets his great-grandson. He believes that fear will cause Dennis’ fangs to sprout and manipulates a stage performer into scaring Dennis, but Drac shields his grandson and exposes Vlad, who is outraged that Drac has accepted humans as guests in his hotel.
Mavis is angered by her grandfather’s treachery and while the family quarrels, an upset Dennis flees the hotel and enters the forest with Winnie in tow, but they are attacked by Bela. When Bela injures Winnie, Dennis instantly grows his fangs and his vampire abilities manifest. Drac, Mavis, and Dennis team up to defeat Bela’s minions. Bela attempts to kill Johnny in revenge, but Vlad appears with a change of heart and shrinks his former servant to a harmless size. With Dennis a pure-blood vampire, Mavis decides to continue raising her son in Transylvania and the party resumes.
