Álex Guzmán is the wronged man at the heart of the story, a former personal trainer to the Lazcanos who spent eighteen years behind bars for a death he insists he never caused. When he emerges from prison, he is hardened, methodical, and singularly focused on exposing the family he blames for destroying his sister Sara and stealing his youth.
His revenge plot is precise and patient, built on surveillance, manipulation, and a deep understanding of the Lazcanos' weaknesses. Yet the deeper he digs, the more his certainties crumble, and his quest for justice repeatedly collides with the unsettling truths he uncovers about Sara's hidden life and fragile mind.
Across three seasons, Álex evolves from a vengeful avenger into a man desperate simply to know what really happened to the sister he adored. His pain, restraint, and flashes of fury make him the moral and emotional engine of every twist the series throws at him.
