The film tells the story of a young accountant (played by Ellan) who is remanded for embezzlement and may face 10 to 20 years in prison, a disproportionate sentence due to the nature of his crime. However, this was 1977, in Modelo prison, and it was a case of survival of the fittest. Although everything was not conducive to his acquittal, the young man refused to dive and joined a group of prisoners who were preparing to request a pardon. If the situation outside the prison is changing, it must also change inside the prison. This became the "Combat Prisoners Coordination Council".
