Synopsis

Violent thunderstorms have begun to plague the island of Berk, and many whisper that Thor himself is angered by the people. The superstitious villagers, driven by the creeping dread of mildew, have turned to a darker explanation, blaming Toothless—the unnatural child born of lightning and death—for the destructive storms. This leaves Hiccup with the daunting task of uncovering the true cause of the god’s sudden wrath.
