Ember is a man-made city built underground to shelter a human community for 200 years. A box has been provided which has a plastic card and instructions for returning to the surface. But it opens automatically after 200 years only. Mayors of the Ember city keep this box as a secret thing and only reveal its existence only to their successors in office. After some decades, this city faces some shortage of food and power and unfortunately the box gets after the death of a Mayor. Now the people in the city are helpless in getting to the surface.
In the meanwhile, Lina (Saoirse Ronan) and Doon (Harry Treadaway) are two kids who are searching for jobs and they love to serve the city of Ember. Soon Lina becomes a messenger and is quite happy to serve her city and Doon gets his job as a pipe worker — the kind of profession that he always loves and has vast knowledge about the city. Soon they come to know about the worse situation of the city. They alsolearn that their Mayor Cole (Bill Murray) doesn’t possess the box.
Unexpectedly, Lina finds the box and with the help of Doon and his elderly mentor Sul (Martin Landau), they try to find the way out of the city. During their mission, Mayor Cole misunderstands the kids, assuming that they stole the box for their own benefit. Can these kids save their people? Will they find out the way to the surface?
