The film tells the story of a young accountant (Herrán) on remand pending trial for embezzlement and possibly facing 10 to 20 years in prison, a disproportionate sentence for the nature of his crime. However, this is 1977 and inside the Modelo prison it is a case of survival of the fittest. Despite everything working against his acquittal, the young man refuses to dive up and joins a group of prisoners preparing to demand amnesty. If things are changing outside the prison, they must also change inside. This becomes COPEL, the Coordination of Fighting Prisoners.

改编自小说《怒火岁月 La edad de la ira》又名愤怒的时代
