A sudden attack by Wulf, a clever and traitorous lord of Rohan seeking vengeance for the death of his father, forces Helm Hammerhand, the King of Rohan, and his people to make a daring last stand in the ancient stronghold of the Hornburg.

'The Lord of the Rings: The War of the Rohirrim' is lauded for its unique animation style and strong voice acting. The music and score are praised, yet the story is criticized for being simplified and rushed. Character development is seen as lacking, and animation consistency is questioned. Pacing and length are contentious, but the film's expansion of Middle-earth is appreciated.
