When a young girl eager to go out trick-or-treating is ditched by her scheming cousin in the basement of an old dark house, a creepy new friend takes her to the ultimate Halloween party in this spooky animated tale directed by Ezekiel Norton and based on the books by Jill Thompson. Hannah Marie was all set for a fun evening of candy gathering when her mean cousin Jimmy leaves her all alone in the dark basement of a spooky mansion. Hannah Marie's Halloween isn't over yet though, because when her Scary Godmother finds the scared young girl, she spirits her away to the most happening Halloween party this side of Transylvania. If a night partying with Harry the Werewolf, Skully Pettibone, and Bug-A-Boo, and the rest of her Scary Godmother's spooky friends isn't enough to brighten the spirits of young Hannah Marie, a plan with her newfound friends for the ultimate revenge against Jimmy the bully will surely make this the most memorable Halloween ever.
