In a present-day Spain, divided and on the brink of political chaos, inquisitive millennial investigative reporter Antonia stumbles on a decades-old conspiracy: the existence of a cryogenically frozen super-agent, García, created in a laboratory in the 1950s by General Franco’s fascist secret services. The old-world collides with the new as García and Antonia must learn to work together as they are drawn deeper and deeper into a political conspiracy that threatens to overthrow democracy and plunge Spain back into brutal dictatorship.

Lucía (Belén Rueda) is a woman for whom leading a model life and taking control of her life is the most important thing. Since she got married, she has focused all of her efforts on caring for her family, until achieving what for her is a perfect family.
