The film opens at the iconic monster resort run by Count “Drac” Dracula, his daughter Mavis and her husband Johnny. Although the hotel has thrived and humans and monsters have learned to coexist, Drac begins to feel that something’s missing. The excitement of the early days is gone, and he wonders if he’s lost his place in the pack. Meanwhile, strange invitations arrive from far‑flung monster families inviting Drac and his friends to an unexpected global “Monster Reunion” summit, held once every century and never open to humans.
Eager for adventure and a chance to reclaim his monster‑leader status, Drac brings the whole crew—Wayne the were‑wolf, Frankenstein (Frank), Murray the mummy, Griffin the invisible man and Wayne’s gigantic wolf pack—to the remote island venue of the summit. What begins as a fun gathering quickly turns mysterious as the monstrous delegates reveal a hidden agenda: a shadowy figure known only as “The Phantom” wants to rewrite monster history by forcing monsters to renounce their powers and assimilate with humans. The Phantom believes that monsters should no longer hide; the world must forget the “monster identity” and become one unified species.
As panic spreads throughout the reunion, Drac and his old‑school pack must team up with younger monsters like Dennis (Mavis & Johnny’s son) and Winnie (Wayne’s daughter) to protect monster culture. Comedy ensues when human guests accidentally wander into the summit disguised as monsters, leading to chaos, cross‑transformations, and plenty of loveable mayhem. Bonding moments abound: Frank learns to accept his hairy self, Murray confronts his ancient past, and Winnie shows Drac that leadership can look very different in a new era.
The emotional core of the story lies in Drac’s struggle with feeling obsolete and the younger generation’s fear of losing their monster heritage. As The Phantom’s plan accelerates, Drac realises that being a monster is not just about fangs or fur — it’s about family, tradition, and embracing one’s weirdness. With the help of his family and friends, Drac crafts a bold plan: crash the summit’s power source, rally the monster delegates to reject The Phantom’s narrative, and stage a spectacular monster‑style showdown under a blood‑moon eclipse.
In the climax, the pack uses classic monster ingenuity (fog machines, howls, mummy wraps, invisible pranks) to thwart The Phantom’s technology and restore the old monster–human balance. Drac embraces his role not just as hotel‑owner, but as mentor to the next generation. The film ends back at the hotel, now buzzing with new adventures, the monster family reunited stronger than ever—and Drac finds a renewed sense of purpose, ready for whatever comes next.
