Five years after uniting the dragons and Vikings of Berk, Hiccup and Toothless soar beyond their homeland, charting the vast unknown. During one of their adventures, the pair discover a secret cave that houses hundreds of wild dragons -- and a mysterious dragon rider with a startling connection to Hiccup. And as the ruthless dragon conqueror Drago Bludvist rises to seize control of both dragons and people alike, Hiccup must step into his role as a true leader and, alongside his friends and Toothless, protect Berk from a devastating war.

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.

A man becomes obsessively jealous of his pianist wife and her violinist companion.
