Locked in a building under construction, Pedro remembers his youth.

Walking by the corn fields in the deep cuban farmlands, a filmmaker approaches a group of guajiros which are harvesting corn by bare hand. While they work, they sing songs about broken hearts.

Pedro is a night guard of buildings under construction who spends his hours prowling empty corridors in the company of an old radio. At the end of the workday he returns to his home in the outskirts of the city where Juampi, his little son, awaits him.

Through found archival material, the film seeks to establish a map of the social monitoring of police abuse, while following the journey of two prowlers through the night. One of them will surely be arrested.
