Anyone who knows The Julekalender from TV can now meet the familiar characters in person. Three elves, Frits, Hansi and Günther, are sent to an old elf cave in Jutland near Oluf and Gertrud Sand's house. Their mission is to find the key to the music box that keeps the elf Gammel Nok alive, all while guarding the Big Book, which holds answers to almost everything and must not fall into the hands of the wicked Nåsåer.
One day a mysterious man named Benny knocks on the Sands' door, and he has sinister plans. Gertrud's big box of Christmas decorations and the famous mistletoe also make a return. Gordon Kennedy, Jesper Lohmann and Christian Damsgaard take the stage in the beloved roles.
