During World War II, four children followed their parents to the countryside to avoid the war. These country houses are antique, with a large wardrobe in one of the rooms. One day, several children were playing hide-and-seek. Lucy (Georgie Henley) hid in the closet, but a magical world unexpectedly appeared in front of her-it was covered with snow and deserted. As she walked in the snow, she encountered the man-sheep monster. Other children also entered the magic wardrobe one by one. They learned that the kingdom inside was called Narnia and was being ruled by an evil witch. The witch wanted to kill these outsiders in one go. At the same time, after learning that Narnia was under the dark rule of the witch, these children fought side by side with Aslan the lion to help Narnia start the restoration of the country.
