60-year-old seamstress Cida needs to sign a document at her workplace, but can't read what it says. With the help of her granddaughter's teacher, she becomes interested in literacy and, at the same time, starts questioning things that happen at her job.

A street singer, a former prostitute and her jealous husband, two thieves, a teacher and two children. All strangers. All in the same place. Five stories that could be one: the search for what we call happiness.
