In a world marked by political turmoil and repression, Aurelia, a history teacher in Buenos Aires, lives an apparently tranquil life with her husband and daughter. However, her world begins to crumble when she starts to question what really happened during the darkest years of the military dictatorship in Argentina. She finds a hidden diary that reveals truths about her own past and her family's, leading her on a journey of self-discovery and prompting her to rethink her identity and morality.
As she immerses herself in the investigation, Aurelia faces both internal and external obstacles. On one hand, her husband is reluctant to talk about their past and the mysteries surrounding them; on the other, the social pressure to maintain appearances intensifies. As she delves into history, she begins to connect with others who have suffered in silence, realizing that many continue to live with the weight of guilt and memory.
Through a rich and emotional narrative, the story explores themes of truth, justice, and the need to confront the past in order to move towards the future. As Aurelia fights to uncover the truth, she becomes a symbol of resistance and a voice for those who have been unable to tell their story. In her search, she realizes that sometimes, the hardest history to face is the one we carry within.
