In 1985 Mexico City, a catastrophic earthquake buries thousands. A doctor with a dark past, a journalist chasing fame, and a family in distress risk their lives in rescue attempts. Their efforts become chances to change their own lives.
Six hours after the earthquake, Chave and Pepín find themselves caught off guard by a crucial decision. In Tlatelolco, the relentless efforts and hours spent removing rubble are paying off; Gabriela and Alberto are getting closer to their children. Beto searches for a way out, while Pablo and Lucía hold on as best they can. Meanwhile, in the hospital rubble, the nurses begin to lose hope.
