El Último Piso(2010)

An abandoned building, the tallest in the city, is filled with trash, mold, and vermin, holding secrets that have remained undiscovered for over twenty years. Within its walls lives the architect Alberto Vásquez, a solitary old man, whom some believe to be a ghost. He dwells on the top floor, far from the murmur and noise, yet also grappling with the memories that lead him back to the building he designed and promoted. He internalizes every detail of the building's decline, its intrigues, and its failures.
