The four children in London were sent to live with a professor in the remote countryside to escape the turmoil of World War II, as depicted in CS Lewis' novel. During a game of hide and seek, they stumbled upon a magical wardrobe which served as a portal to the mysterious land of Narnia, ruled by an evil witch. In order to defeat the witch, the children had to join forces with Aslan, the lion deity of Narnia, leading to an epic battle between good and evil. As they embarked on this journey, they discovered the true meaning of courage, friendship, and sacrifice.
