In a world where ancient fairy tales hold a dangerous truth, a family's new home becomes the gateway to a forgotten realm. When curious siblings stumble upon a hidden world of magical creatures right in their backyard, they discover that the charming stories of goblins are far more real—and perilous—than they ever imagined. Voiced by a stellar cast including Yuuichirou Umehara, Yui Ogura, and Nao Toyama, the children must navigate this enchanting yet treacherous land, forging unlikely alliances with its quirky inhabitants while evading those who wish the human world to remain forever separate. Directed by Peter Segal, this family adventure blends whimsy with thrilling stakes, as the young heroes learn that courage and cleverness are their greatest tools. They embark on a quest that tests their bond and challenges everything they thought they knew about the legends lurking in the shadows, all while a deeper mystery about the two worlds' connection begins to unfold.
