Five years have passed since Hiccup and Toothless united the dragons and Vikings of Berk. Now, they spend their time charting the island's unmapped territories. During one of their adventures, the pair discover a secret cave that houses hundreds of wild dragons -- and a mysterious dragon rider who turns out to be Hiccup's long-lost mother, Valka (Cate Blanchett). Hiccup and Toothless then find themselves at the center of a battle to protect Berk from a power-hungry warrior named Drago.
My opinion I loved this film just like I loved the first one. ☺ This one was sad because he lost his father but good because he gained his mother, he also becomes the Chief of the village which is so cool. Over all great film.
