Feeling lonely and overworked, Count Dracula (Adam Sandler) is surprised by his daughter Mavis (Selena Gomez) with a monster-filled family vacation on a luxurious cruise ship. Joined by Johnny (Andy Samberg), Dennis (Asher Blinkoff), and their quirky monster friends, Drac indulges in the ship’s fun, from monster volleyball to exotic excursions. But when he falls for the charming human captain, Ericka (Kathryn Hahn), a “zing” sparks romance—until Mavis discovers Ericka’s secret: she’s the great-granddaughter of Dracula’s nemesis, Abraham Van Helsing (Jim Gaffigan), plotting to destroy all monsters. What starts as a dream getaway turns into a hilarious, high-stakes adventure to save monsterkind.
