When Hiccup and the Dragon Riders go exploring using a new map, their dragons pull them toward an island with entrancing music. It's getting late, so they land and go to sleep. In the morning, the dragons are gone! Hiccup must figure out who is making the music - and how to break the spell - before Toothless and the other dragons are lost forever!
