This is a sad song of losers. After the end of the Spanish Civil War (1936-1939), the defenders of the failed Republic government were rightly sentenced to imprisonment, along with their bodies, along with their voices. The film is mainly about the sad story of a group of women who were jailed by Franco in a bloody crackdown and revenge against the opposition. The works portray a series of female characters with similar origins and different personalities, fail to depict their miserable life in prison, and reflect the heroic spirit of the locals' vows to fight against the reactionary authorities to the end. However, some of these fighters who had suffered a lot in prison were sentenced to death, some died of illness, and very few of them got out of prison. Therefore, they raised a loud slogan: to live, to tell history, to shout. As a result, a "sound of deep sleep" was made.
