Lima, 1988. Two brothers are left alone at home while there is a blackout. One is asthmatic, and the other is afraid of what is hiding in the dark.
We follow Bernabé and Carolina, a married couple in crisis who decide to separate just one day before the quarantine is issued. Bernabé, an epidemiologist by profession and a hypochondriac by vocation, although it sounds contradictory, decides to take shelter in the safest place he knows: his house.
