The three elves ("nisser") Hansi, Fritz, and Günter have to save the dying "Gammelnisse", the only way being to rewind his magic music box. This leads to a hunt for the winding key far, far away in his old "nissehule". Close by, a wife and her husband live a normal life,oblivious to what is happening around them. Things get interesting when an ominous, strange man shows up at their door step late one night, looking for local elves.
