It has been 3 years since the war with the Berserkers and Hiccup and his friends are enjoying life. But, when Dagur the Deranged escapes from the prison on Outcast Island, he decides to take his revenge on Hiccup. Hiccup and the dragon riders, thanks to Johann, band back together and track him down to a fog bank beyond their borders and discover a huge graveyard of ships filled with treasures that Dagur would use to build a new armada. In the commander's quarters of 'The Reaper', Hiccup finds a very mysterious device and after a struggle with Dagur all of the group, apart from Hiccup, are trapped in a cage. Dagur fires a boulder, from a catapult, onto The Reaper causing the ship to sink, leaving Hiccup with a choice: Retrieve the device he found from Dagur, or save his friends from certain death.
Hiccup goes to save the other riders, but discovers that cage is 'Dragon-Proof'. After much effort they finally get it open and Hiccup is able to retrieve the device from a distracted

Hiccup goes to save the other riders, but discovers that cage is 'Dragon-Proof'. After much effort they finally get it open and Hiccup is able to retrieve the device from a distracted Dagur. Back on Berk, Hiccup asks Gobber and Gothi about the device which he dubs 'The Dragon Eye' Gothi tells them that the key to unlocking the 'Dragon Eye' is a tooth from the Snow Wraith (A Strike class Dragon that detects body heat as a form of sight). The riders and Gothi travel to Glacier Island to retrieve the tooth. Meanwhile, Gobber takes Gothi's place as the village healer, however he is far from good at it. Hiccup, after fiddling around with the eye, finds that it's activated by the fire of any Dragon and works as a light projector showing him maps, writing and Dragons he's never seen. He then quotes, "This changes ... everything!"

After the group traps the leader dragon they realise how much danger the rest of the dragons are in when Changewings begin attacking them. They suddenly realise that the Night Terrors, under the command of their Alpha, a white Night Terror, need to flock into a shape of a giant version of themselves or any other dragon they wish as a defense mechanism to scare off threats or predators. The dragon riders fight off the Changewings and free the leader. The leader then befriends the riders as the natural protector of them and the island.

Gothi hypnotizes Fishlegs in an attempt to rid him of the allergy, however, due to Snotlout talking during the hypnosis, Fishlegs thinks he is the all mighty, all-conquering, warrior viking called Thor Bonecrusher who is loved by everyone and has no fear of anything. In Thor's attempt to tame the Scauldron, Meatlug comes under attack, and the fear for Meatlug's safety is the only thing to snap Fishlegs out of the hypnosis. Later, it was discovered that Fishlegs was allergic to Gobber's ear wax which he has been using on Meatlug's saddle.
