On the rugged isle of Berk, where Vikings and dragons have been bitter enemies for generations, Hiccup (Mason Thames; The Black Phone, For All Mankind) stands apart. The inventive yet overlooked son of Chief Stoick the Vast (Gerard Butler, reprising his voice role from the animated franchise), Hiccup defies centuries of tradition when he befriends Toothless, a feared Night Fury dragon. Their unlikely bond reveals the true nature of dragons, challenging the very foundations of Viking society. With the fierce and ambitious Astrid and the village's quirky blacksmith Gobber by his side, Hiccup confronts a world torn by fear and misunderstanding. As an ancient threat emerges, endangering both Vikings and dragons, Hiccup's friendship with Toothless becomes the key to forging a new future. Together, they must navigate the delicate path toward peace, soaring beyond the boundaries of their worlds and redefining what it means to be a hero and a leader.
