A teenage girl moves into a remote country home with her family, only to discover that the gloomy old house has a horrifying past that threatens to destroy them.

Four kids get lost in the forest in the middle of a storm and go take refuge in an abandoned castle. There they will meet and face Dracula, the Werewolf, Quasimodo and Doctor Frankenstein. Despite the attempts of the monsters to scare them and, in passing, recover their lost prestige, the children, with the help of Count Dracula's son, will face the evil creatures.
