Theme
Lina's teacher at Assignment Day ceremony speaks about how "everyone has their part to play" in keeping Ember alive, establishing the theme of individual responsibility versus collective survival and the tension between hope and fear.
Worldbuilding
Assignment Day ceremony where graduates receive their jobs. Lina is assigned Pipeworks (underground), Doon gets Messenger (desired by Lina). We see Ember's infrastructure failing: flickering lights, food shortages, crumbling buildings. The citizens are kept ignorant of their true situation.
Disruption
Lina and Doon trade jobs. Doon descends into the Pipeworks and discovers the generator is catastrophically failing—massive machinery breaking down, leaks everywhere. He realizes Ember has very little time left before permanent blackout.
Resistance
Lina finds fragments of an ancient document ("Instructions for Egress") chewed by her baby sister. Doon tries to fix the generator but realizes it's beyond repair. Both independently realize they need to find a way out. Lina debates whether to trust Doon; Doon debates whether escape is even possible.

Lina and Doon's partnership deepens as they work together to decode the instructions. Their collaboration represents the film's theme: two people with different skills (Lina's hope and speed, Doon's technical knowledge) can achieve what neither could alone.
Premise
The "fun and games" of decoding the mystery: Lina and Doon explore forbidden areas, piece together clues, discover the Mayor is hoarding supplies in a secret bunker, and begin mapping a path through the Pipeworks following the instructions. They experience the thrill of discovery and rebellion.
Midpoint
False defeat: Lina and Doon are discovered and pursued by guards. The Mayor publicly denounces them as troublemakers spreading dangerous lies. The city turns against them, and their evidence is confiscated. Stakes raise dramatically—now they're fugitives with the clock ticking faster.
Opposition
The Mayor intensifies his hunt for Lina and Doon. The generator failures worsen—blackouts become longer and more frequent. Citizens panic. Lina and Doon must evade guards while continuing to decode the instructions. They face setbacks, wrong turns, and growing doubt.
Collapse
The generator suffers a catastrophic failure, plunging Ember into extended darkness. Citizens riot. Lina's grandmother dies, representing the death of the old generation and the old ways. Lina and Doon are separated and nearly captured. All seems lost—the city is dying and they're no closer to escape.
Crisis

Synthesis
The finale: Lina, Doon, and Poppy navigate the Pipeworks, find the hidden boat, ride the underground river, and climb up through the exit pipe. The Mayor tries to follow but fails. They emerge onto the surface, seeing the sky and ruins of the old world for the first time. They send the instructions back down to Ember via rock drop.
Transformation
Final image mirrors the opening: Instead of the dark, enclosed city, Lina and Doon stand in sunlight on the surface, looking out at the vast world.
