The thrilling second chapter of the epic How To Train Your Dragon trilogy brings back the fantastical world of Hiccup and Toothless five years later. While Astrid, Snotlout and the rest of the gang are challenging each other to dragon races (the island’s new favorite contact sport), the now inseparable pair journey through the skies, charting unmapped territories and exploring new worlds. When one of their adventures leads to the discovery of a secret ice cave that is home to hundreds of new wild dragons and the mysterious Dragon Rider, the two friends find themselves at the center of a battle to protect the peace.

A group of attractive young people (of course) awaken to find themselves prisoners in a mysterious house with no means of escape. They are each outfitted with new accouterments–electronic devices attached to the base of their skulls–and a recording on a television screen alerts them of their task. In order to escape, they must hurt themselves and each other. The chemicals that the brain produces when in pain are collected by the devices, and when it collects a predetermined amount, the doors will be opened. Fail to do it in time, and everybody dies.

Teaming up for the first time for a special episode of a supernatural reality TV show, two rival crews get more then they bargained for when they make physical contact with a ferocious spirit of terrifying power. They must band together before it destroys them all. After 49 killer episodes…this is the true story of what happened on episode 50.

As the son of a Viking leader on the cusp of manhood, shy Hiccup Horrendous Haddock III faces a rite of passage: he must kill a dragon to prove his warrior mettle. But after downing a feared dragon, he realizes that he no longer wants to destroy it, and instead befriends the beast – which he names Toothless – much to the chagrin of his warrior father
