The short film is set in an alternative present in a western country where the government has issued a series of laws to combat the phenomenon of birth rate and, at the same time, the overcrowding of the planet.
Every year, women are required to declare to the state whether they have had a child and, if not, why they are not doing so. If they reach the age of 47 without children, the government "withdraws" the badge, the tag that allows Bianca to live and study music, and in doing so women disappear from circulation.
