How to Train Your Dragon: The Hidden World (2019) is the final chapter in DreamWorks’ beloved animated trilogy, directed by Dean DeBlois. The film delivers an emotionally rich and visually breathtaking conclusion to Hiccup and Toothless’s decade-long journey. It’s not just about dragons and battles — it’s about growing up, letting go, and learning when love means setting someone free.
Detailed Summary
The New Berk and Its Dragon Haven
The film opens with Hiccup (voiced by Jay Baruchel) leading daring rescue missions to save captured dragons from trappers. Berk has now transformed into a dragon utopia, with dragons living freely among humans. However, this paradise is getting overcrowded, and Hiccup is struggling to keep harmony between dragons and villagers.
Meanwhile, Astrid (America Ferrera) remains Hiccup’s closest ally — and soon-to-be wife — providing both emotional strength and practical leadership.
Enter the Villain: Grimmel the Grisly
The film’s antagonist, Grimmel the Grisly (voiced by F. Murray Abraham), is a ruthless dragon hunter who prides himself on having killed every Night Fury except Toothless. Grimmel learns of Toothless’s existence and decides to hunt him down, using a captured female Light Fury as bait.
Grimmel’s arrival introduces a darker, more menacing tone, symbolizing the end of the age of dragons.
The Light Fury and a Love Story in the Skies
One of the most touching parts of the film is Toothless meeting the Light Fury, a luminous, elegant dragon who captures his heart immediately. Their courtship scenes are both charming and hilarious, especially Toothless’s awkward mating dance, which is one of the film’s standout sequences.
This subplot beautifully mirrors Hiccup’s own growth — Toothless begins to find independence, while Hiccup faces the painful truth that their paths might soon diverge.
The Search for the Hidden World
Hiccup remembers tales his father Stoick once told him about the “Hidden World,” a mythical place beneath the sea where dragons live in peace, away from human reach. Believing this could be a new sanctuary, Hiccup leads the Berkians and their dragons on a perilous journey to find it.
This journey is full of discovery and danger, as Hiccup wrestles with the dual burdens of leadership and love.
Battle with Grimmel
Grimmel captures Toothless and the Light Fury using his cunning tactics. The tension peaks as Hiccup, Astrid, and their allies launch a daring rescue mission to free them. The final showdown takes place high in the sky, filled with stunning visuals and emotional stakes.
In the end, Hiccup outsmarts Grimmel, sacrificing his own safety to save Toothless. Grimmel falls to his death, taking his dragons with him — a poetic ending for a character consumed by obsession.
Movie Ending
After the battle, Hiccup realizes that as long as humans and dragons live together, dragons will never be safe. In a heartbreaking yet mature decision, he tells Toothless that he must go to the Hidden World — where dragons can live freely, away from human greed and conflict.
The farewell scene between Hiccup and Toothless is one of the most emotional in the entire series. Hiccup removes Toothless’s saddle, touches his snout one last time, and whispers, “Go.” Toothless hesitates but finally flies off with the Light Fury, disappearing into the clouds. The bond between them remains unbroken, but their paths must part.
Years later, in a touching epilogue, we see an adult Hiccup and Astrid, now married with two children. They sail to the edge of the world and reunite with Toothless, who now has a family of his own — three adorable Night Lights (hybrid offspring of Toothless and the Light Fury). The reunion is filled with warmth and nostalgia, affirming that true friendship and love endure, even across worlds.
The final shot shows both families flying together through the skies, echoing the theme that began the trilogy: freedom, trust, and the unbreakable bond between dragon and rider.
Are There Post-Credits Scenes?
No, there is no post-credits scene in The Hidden World. The movie ends with the emotional reunion epilogue. However, the ending itself serves as a beautiful closure, leaving no need for extra scenes. Still, a short DreamWorks logo animation featuring Toothless may appear after the credits, serving as a subtle goodbye.

Filming and Animation Locations
Although fully animated, the visual inspiration for the landscapes — from Berk’s rugged cliffs to the bioluminescent caverns of the Hidden World — came from Norwegian fjords, Icelandic coastlines, and the northern lights.

Behind the Scenes Insights
- Director Dean DeBlois confirmed that the trilogy was always meant to end with dragons leaving the human world, mirroring the book’s bittersweet tone.

Inspirations and References
The film is loosely based on Cressida Cowell’s book series, though the story diverges greatly in tone and plot. The themes of growing up, leadership, and letting go were inspired by the director’s own reflections on parenthood and creative closure.
Alternate Endings and Deleted Scenes
Early drafts of the film included a version where Hiccup would stay connected to the dragons via a portal to the Hidden World. However, Dean DeBlois decided against it, believing that a permanent separation would be more emotionally powerful and thematically honest.
Some deleted scenes expand on the villagers adjusting to life without dragons but were cut for pacing.
Book Adaptations and Differences
In Cowell’s books, the story is told from an older Hiccup’s perspective, looking back on how dragons disappeared. The movie condenses that idea into a visual narrative, focusing more on Hiccup and Toothless’s friendship and emotional journey than the political or historical aspects found in the novels.
