Fernando Eimbcke returns to his cinematic roots with a black-and-white masterpiece that finds profound beauty in the most ordinary  moments of daily life. Olga lives a strictly regulated life without attachments in a vast apartment block. When out of financial necessity she rents a room in her apartment to a man who also sneaks-in his nine-year-old son.  Her carefully controlled world begins to shift, and their lives become intertwined against her will. The little boy arrives like the persistent buzzing of an irritating fly she desperately wants to get rid of, yet his guileless charm and sheer persistence gradually crack her hardened shell, sparking an unexpected transformation.
