A group of adolescent monster movie enthusiasts form a club that meets in a treehouse in this pre-teen horror feature. When Dracula, The Mummy, Frankenstein, and The Wolfman are joined by Gill-Man in the search for a magic amulet, the boys form the Monster Squad to battle the forces of evil. The boys get unexpected help from Frankenstein when the monster grows tired of being continually bossed around by Dracula.
