Synopsis: 

Juan Esteban and Carolina are a young couple who have made their home in an apartment in a building ruined by an earthquake. Driven by fear of hauntings, Carolina decides to leave. Juan Esteban remains alone, deeply attached to the place. In his grief, he lives with this spectral ecosystem of noises and shadows, becoming one of them. Carolina's absence begins to resonate like an echo. One night, he ventures out into the building searching for traces of her presence and discovers that she, too, has become his ghost.
