of an aging José (Héctor Alterio), Ernesto Olaya (Eduardo Blanco), is an unemployed architect in Buenos Aires who is suffering from the precursor to the economic crisis of that year. He decides to emigrate to Spain with his wife and children, but the Corralito, a bank restriction imposed by the government, blocked his bank deposits, preventing him from buying four plane tickets. However, his father offers him enough money to travel alone. Ernesto moves to Madrid, where he meets Ana (Marta Etura), a twenty-something year old waitress who helps him settle into a shared apartment with Mara (Angie Cepeda), a young illegal immigrant from Colombia. Ernesto watches how his plans of progress crumble in the midst of a slow Spanish bureaucracy. His progress is also deterred by the restrictions and xenophobia suffered by immigrants. Despite this, he lies to his family about his true situation, making them believe that he lives alone and with good job expectations. Returning to the past, José embarks on his journey to Argentina, meeting Julius Lazlo (Pablo Rago), a young Hungarian Jew and Gemma (Francesca Trentacarlini/Giulia Michelini), a nine-year-old Italian girl who lost her family. Together they are placed in a tenement in the La Boca neighborhood. The plot continues during the 1940s and 1950s, showcasing José dealing with the outbreak of the Spanish Civil War, the love story between Julius and Gemma, and the political landscape of Argentina during Peronism. In addition, it shows José’s relationship with the different women in his life, like his first wife Sophie (Caterina Murino) and his second wife, Lucía (Valeria Bertuccelli), who ends up being Ernesto's mother. For his part, Ernesto temporarily gets an illegal job in an architects' studio. Due to his lack of sincerity and the long separation from his family, irritations begin to emerge between Ernesto and his wife Cecilia (Claudia Fontán), who begins an extramarital relationship with a colleague at work. At the end of the series, Cecilia and Ernesto divorce. Ernesto then begins to have feelings for his roommate Mara, and they end up getting married and having a child together. Finally, in 2005, Ernesto — who already enjoys dual nationality and stable work as an architect — and his father visit Asturias. While there, José meets the ghosts of his past. He considers killing the foreman who sent his brother to the mine 70 years ago but has a change of heart.
