Barbie and the Secret Door  Barbie and the Secret Door is a 2014 American-Canadian direct-to-video computer-animated musical fantasy film, and the 28th entry in the Barbie film series. This film is directed by Karen Lloyd and features the voice of Kelly Sheridan as Princess Alexa, a shy princess who discovers a secret door in her kingdom and enters a whimsical land filled with magic-induced creatures. Set in a modern-day kingdom, Alexa is a shy, book-reading princess who avoids doing the duties expected of her due to her rank. In order to encourage her, Alexa's grandmother gives her a storybook about a princess who discovers she has magic. While reading the book, Alexa discovers a mysterious door in the royal gardens. She enters the door and finds herself in a fantasy land. Alexa meets Nori, a fairy missing her wings, and Romy, a mermaid with legs instead of her tail. Nori and Romy are thrilled because as a princess, Alexa can perform magic with a wand. Their realm is under threat by the mean Princess Malucia, a spoiled child princess who was born without magic and has been taking it by force from all the creatures she can capture. Alexa is brought to the glade where fairies, mermaids and unicorns are hiding from Malucia. There, Alexa slowly learns to use her wand. However, she cannot return Nori and Romy to their original forms, because their magic is trapped in Malucia's scepter. The group learn that Malucia is trying to find the Queen Unicorn, who is the most magical creature in the realm. Alexa, Nori, and Romy travel to the Queen Unicorn, hoping to protect her, only to unintentionally lead Malucia and her minions right to her. Malucia captures the Queen Unicorn, while Nori and Romy provide a distraction so that Alexa can escape. While fleeing, Alexa discovers the doorway back to her world but decides to stay and help. Alexa, Nori, and Romy go to Malucia's palace, where they witness Malucia draining all the unicorns' magic into her scepter. Alexa confronts Malucia, declaring that she is a princess, too, which provokes Malucia into a magical battle to "prove" who is the better princess. During the fight, Alexa realizes that Malucia's scepter is cracking under its magical content. Alexa willingly lets Malucia steal all her magic, which causes Malucia's scepter to explode, releasing all its magic.
