In Marrowhold, a terraced village wedged into a frozen valley, life depends on the Ember Beacon: a great brazier atop a stone spire whose heat keeps the encroaching glacier at bay. When an avalanche shears the spire and drowns the beacon in snow, the valley begins to freeze shut within hours — doors icing, wells crusting, the glacier grinding closer with each nightfall. Eleven-year-old NIX, apprentice to the lamplighters, steals the last surviving coal from the temple hearth and seals it in a brass lantern; her grandfather HOLLAND, a retired beacon-keeper going blind, insists on guiding her by memory of a road he walked forty years ago. They set out with a cargo sledge and MOSS, a shaggy sled-dog. Crossing the Glass Flats, they discover the ice is honeycombed and hollow, and a huge translucent-furred bear — the LANTERN BEAR, whose hollow pelt glows with whatever heat it swallows — begins tracking the only warm thing for miles. In the middle act the pair are separated: Nix falls through a crust into a cathedral of blue meltwater caves, where she finds the old sunken lamp road and the bones of the last expedition, while Holland, unable to see, tracks her by sound and by Moss. They reunite at the Skeleton Bridge, where a scavenger, TARRIN, ambushes them for the lantern — he wants to sell warmth, not give it — and in the struggle the coal is dropped into the snow and nearly dies. Nix saves it by feeding it her own woolen coat, and the bear, drawn by the flare, tears the bridge apart; Tarrin is spared by Nix and, shamed, hauls the sledge with them. In the climb up Marrowhold Spire the bear finally corners them on the icy stair, and Holland realizes what the animal actually wants: it is not hunting them, it is dying of cold, its hollow pelt empty. Nix makes the film's single great decision — she splits the ember, giving half to the bear's cage-like chest cavity and carrying half upward. The bear, blazing gold from within, becomes their light on the dark stair. The beacon relights at dawn; the glacier's leading edge cracks and retreats, meltwater roars through the terraces, and the village wakes to warmth. The final image is the Lantern Bear walking out across the flats, a slow moving star, with Nix's lamplighter pole planted in the snow behind it.
