Emma, Hernán and Teresa live inside a tall building where there is no way out. A strange and powerful presence, the Heights Dweller, keeps all trapped for ever against their will as they go on with their life without any knowledge of their imprisonment. These three characters must find out the truth and do whatever is in their power to get out. However, the Heights Dweller is always watching, ready to use the force to drown any seed of rebellion.

Because of the small budget, it took four years for the filmmakers to complete the movie.

Almost six different montage versions where tried before the final one, and twenty minutes were cut out.
